FN7668 Rev 0.00 December 23, 2011 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 VDD 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 VDD. The HIP2121 has 3.3V logic/TTL patible 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 ply with 100V conductor spacing per IPC-2221.
