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

Adjustable Dead Time Control and PWM Input

HIP2120, HIP2121

Features

• 9 Ld TDFN “B” Package Compliant with 100V Conductor

Spacing Guidelines per IPC-2221

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.

• Break-Before-Make Dead-Time Prevents Shoot-through and is

adjustable up to 220ns

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.

• Bootstrap Supply Max Voltage to 114VDC

• Wide Supply Voltage Range (8V to 14V)

• Supply Undervoltage Protection

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

• CMOS Compatible Input Thresholds with Hysteresis (HIP2120)

• 1.6Ω/1Ω Typical Output Pull-up/Pull-down Resistance

• On-Chip 1Ω Bootstrap Diode

logic inputs are V tolerant and the HIP2120 has CMOS inputs

with hysteresis for superior operation in noisy environments.

The HIP2120 has hysteretic inputs with thresholds that are

proportional to V . The HIP2121 has 3.3V logic/TTL compatible

inputs.

Applications

• Telecom Half-Bridge DC/DC Converters

• UPS and Inverters

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.

• Motor Drives

• Class-D Amplifiers

• Forward Converter with Active Clamp
