100V, 2A Peak, High Frequency Half-Bridge Drivers with Rising Edge Delay Timer
HIP2122, HIP2123
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.
