The best choice depends on whether you need a dedicated high-side driver, a half-bridge driver, or a protected high-side power switch. The FAN7371MX is the most directly relevant dedicated high-side option in this selection; the IR2101 and IRS2092S provide high- and low-side outputs for half-bridge applications. The BTS410E2 is a high-side switch rather than a conventional external MOSFET gate driver, while the TC4420 is a general MOSFET driver whose supplied listing does not establish high-side capability.
| Product | Best suited for | Key distinction |
|---|---|---|
| FAN7371MX | Dedicated high-side drive needs | High-side driver, 8-SOP |
| IR2101PBF | Half-bridge circuits | High- and low-side outputs |
| IRS2092S | Class D audio amplifier boards | Half-bridge driver with audio functions |
| BTS410E2 | Protected high-side load switching | High-side switch IC |
| TC4420 | General MOSFET drive tasks | High-side use not established |
FAN7371MX High-Side Gate Driver
The FAN7371MX is the most straightforward match for a search focused specifically on high-side gate-driver ICs. The listing identifies it as a high-side gate driver in an 8-SOP package and notes RoHS compliance and cut-tape packaging.
Best for: Buyers who need a dedicated high-side driver in a compact surface-mount package. It was selected because its listed device type directly matches the requested function.
Check before ordering: The supplied product details do not specify operating voltage, peak drive current, or pinout. Verify these against the manufacturer documentation and your circuit requirements before choosing it.
IR2101PBF High- and Low-Side Driver
The IR2101PBF listing describes a five-piece set of IR2101 DIP-8 chips with high- and low-side referenced outputs. That output arrangement makes it a candidate for circuits that need both sides of a half-bridge driven, rather than only a standalone high-side channel.
Best for: Buyers building or repairing a half-bridge and seeking through-hole DIP-8 parts. It was selected for its explicitly listed high-side output.
Check before ordering: The supplied listing does not give electrical ratings or detailed pin information. Confirm the exact part number, package, and datasheet requirements; avoid assuming it matches another driver solely because the package looks similar.
IRS2092S Class D Half-Bridge Driver
The IRS2092S combines an analog input stage, PWM modulator, and floating high-side/low-side gate driver for half-bridge MOSFETs. Listed details include a 10–18 V low-side supply, 1.0 A source and 1.2 A sink drive strength, selectable deadtime, over-current protection, and UVLO. Its package is narrow SOIC-16 SMD.
Best for: Class D audio amplifier repair or design where the complete audio-driver feature set is relevant. It was selected because its specified floating outputs include high-side drive.
Check before ordering: Confirm IRS2092S marking, board footprint, pinout, and supply rails. This is an SMD component, and installation requires suitable handling and soldering equipment.
Infineon BTS410E2 High-Side Switch
The BTS410E2 listing identifies a high-side device in a TO-220AB5 package, with a stated 4.7–42 V supply range and 1.8 A peak output current. It is better understood as a high-side switch for driving a load than as a gate driver for an external MOSFET.
Best for: Buyers seeking an integrated high-side switching device and whose load and supply requirements fit the listed specifications. It was included because its high-side function is relevant, although it is not a like-for-like replacement for a gate-driver IC.
Limitation: Choose another product if your circuit specifically needs a separate driver output to control an external MOSFET gate.
TC4420 High-Speed MOSFET Driver Set
This listing offers 10 TC4420-family chips in DIP-8 packaging and describes them as high-speed MOSFET drivers. The supplied details do not identify a floating output or specify high-side operation, so this part should not be treated as a confirmed high-side driver based on the listing alone.
Best for: Buyers who need the listed general MOSFET-driver part and can independently confirm it suits their circuit. It was selected as a related option, not as a direct high-side recommendation.
Limitation: Avoid choosing it for high-side switching without checking the manufacturer datasheet and circuit topology.
Buying Guide: How to Choose a High-Side Driver
Do you need a gate driver or a high-side switch?
A gate driver controls the gate of an external MOSFET. A high-side switch is an integrated device that switches power to a load. The BTS410E2 belongs to the latter category in the supplied product information. Choose a dedicated driver such as the FAN7371MX or a half-bridge driver when your design requires external MOSFET gate control.
Is your circuit a single high-side channel or a half-bridge?
A half-bridge uses high-side and low-side switches, so an IC with both outputs, such as the listed IR2101 or IRS2092S, may fit that topology better. A dedicated high-side driver may be more suitable when the requirement is only a high-side channel. Match the circuit to the IC’s datasheet rather than relying on category labels.
Which electrical and package details should you verify?
- Supply and voltage ratings: Compare the IC’s documented operating range with the system and switching-node voltages.
- Drive current: Check source and sink capability against the MOSFET gate-charge and switching-speed needs.
- Package and mounting: Confirm DIP, SOIC, SOP, or TO-220 details match the board and assembly method.
- Protection and timing: Review features such as UVLO, over-current protection, and deadtime when the circuit requires them.
- Exact part number: Verify pinout and markings before replacement; similar names do not guarantee interchangeable parts.
Frequently Asked Questions
What does a high-side gate driver do?
It provides the control signal needed to switch a high-side transistor, whose source or emitter is not fixed at ground. The appropriate circuit depends on the transistor type and switching arrangement.
Is the BTS410E2 a MOSFET gate driver?
The supplied listing describes it as a high-side switch. It should not be assumed to drive an external MOSFET gate like a dedicated gate-driver IC.
Can a half-bridge driver control a high-side MOSFET?
Yes, a half-bridge driver with specified high-side and low-side outputs is designed to serve both positions. Confirm its voltage limits, supply requirements, and external circuit needs in the datasheet.
Is the TC4420 a confirmed high-side driver?
The supplied product details call it a high-speed MOSFET driver but do not establish high-side capability. Verify the exact datasheet and intended topology before use.
What should I check before replacing a driver IC?
Match the exact part number, pinout, package, supply range, output ratings, and circuit function. Also check surrounding components and board condition before installing a replacement.
