HIP2121

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 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 compatible 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.

Decouple this pin with a ceramic capacitor to VSS. High-side bootstrap supply voltage referenced to HS. Connect the positive side of the bootstrap capacitor to this pin. Bootstrap diode is on-chip. High-side output. Connect to gate of high-side power MOSFET. High-side source connection. Connect to source of high-side power MOSFET. Connect negative side of bootstrap capacitor to this pin. PWM input. For PWM = 1, HO = 1 and LO = 0. For PWM = 0, HO = 0 and LO = 1. Output enable, when low, HO = LO = 0 Negative voltage supply, which will generally be ground. Low-side output. Connect to gate of low-side power MOSFET. No Connect. This pin is isolated from all other pins. A resistor connected between this pin and VSS adds additional delay time to the falling and rising edges of the PWM input. Exposed pad. Connect to ground or float. The EPAD is electrically isolated from all other pins. Ordering Information PART NUMBER (Notes 1, 2, 4) HIP2120FRTAZ HIP2121FRTAZ HIP2120FRTBZ (Note 3) HIP2121FRTBZ (Note 3) NOTES: 1.
