100V, 2A Peak, High Frequency Half-Bridge Drivers with

Adjustable Dead Time Control and PWM Input

HIP2120, HIP2121

The HIP2120 and HIP2121 are 100V, high frequency, half-bridge

MOSFET driver ICs. They are based on the popular ISL2100A and

ISL2101A half-bridge drivers.

These drivers have a programmable dead-time to insure

break-before-make operation between the high-side and low-side

drivers. The dead-time is adjustable up to 250ns.

A single PWM logic input controls both bridge outputs (HO, LO). An

enable pin (EN), when low, drives both outputs to a low state. All

logic inputs are V

with hysteresis for superior operation in noisy environments.

The HIP2120 has hysteretic inputs with thresholds that are

proportional to V

inputs.

Two package options are provided. The 10 Ld 4x4 DFN package has

standard pinouts. The 9 Ld 4x4 DFN package omits pin 2 to comply

with 100V conductor spacing per IPC-2221.
