100V, 2A Peak, High Frequency Half-Bridge Drivers with Rising Edge Delay Timer

Rev 0.00

December 23, 2011

The HIP2122 and HIP2123 are 100V, high frequency, half-

bridge MOSFET driver ICs. They are based on the popular

ISL2100A and ISL2101A half-bridge drivers. Like the

ISL2100A, two logic inputs, LI and HI, control both bridge

outputs, LO and HO. All logic inputs are VDD tolerant.

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 220ns. The

internal logic does not prevent both outputs from turning on

simultaneously if both inputs are high simultaneously for a

time greater than the programmed delay.

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 VDD tolerant and the HIP2122 has

CMOS inputs with hysteresis for superior operation in noisy

environments.

The HIP2122 has hysteretic inputs with thresholds that are

proportional to VDD. The HIP2123 has 3.3V logic/TTL

compatible inputs.

Two package options are provided. The 10 lead 4x4 DFN

package has standard pinouts. The 9 lead 4x4 DFN package

omits pin 2 to comply with 100V conductor spacing per IPC-

2221.
