Detailed Description

Half-bridge gate driver for N-channel MOSFETs (high-side + low-side)

Two independent non-inverting input channels

2 A peak source/2 A peak sink gate drive

High-side bootstrap operation up to 118 V

Supply (VDD) 9 V to 14 V (typical 12 V gate-drive bias)

10-WSON (4 x 4 mm) with exposed thermal pad; surface-mount

Operating junction temperature -40°C to +125°C

RoHS3 compliant

Packaging: Tape & Reel (TR)

Base product number: LM5101

Key Features

Half-bridge driver with independent inputs (flexible dead-time control in firmware or controller)

Drives N-channel MOSFETs (both high-side and low-side)

Peak output current: 2 A source, 2 A sink

High-side bootstrap rating: up to 118 V

Input type: non-inverting; logic-friendly thresholds (see datasheet)

Typical rise/fall times: 570 ns / 430 ns (load-dependent)

Wide operating TJ range: -40°C to +125°C

Compact 10-WSON (4x4) with exposed pad for lower thermal resistance

RoHS3 compliant, lead-free

Key Advantages

Simple, robust half-bridge MOSFET drive up to 118 V systems

Strong 2 A gate-drive current improves switching of medium-power MOSFETs

Independent inputs simplify PWM control schemes and custom dead-time

Small, thermally enhanced package saves PCB space and helps heat dissipation

Works well with common 12 V gate-drive bias rails

Broad ecosystem and app notes from TI for quick design-in

Packaging

Type: Tape & Reel (TR) for automated assembly

Package family: 10-WSON (4 x 4 mm), also referred to as 10-WDFN with exposed pad

Material: Molded plastic package, copper leadframe, lead-free plating (RoHS3 compliant)

Size: Body ~4.0 mm x 4.0 mm; low-profile height

Pin configuration (typical functional pins; see datasheet for exact map): HI (high-side input), LI (low-side input), HO (high-side gate), LO (low-side gate), HB (bootstrap supply), HS (switch node return), VDD (bias), VSS/GND, and NC pins

Thermal characteristics: Exposed thermal pad on bottom; solder the pad to a ground plane with thermal vias for best thermal performance; follow TI land-pattern and reflow guidelines

Electrical properties summary: VDD 9–14 V, high-side bootstrap to 118 V, outputs 2 A/2 A source/sink, non-inverting logic, rise/fall 570 ns/430 ns (typ)
