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.
Features
• 9 Ld TDFN “B” Package Compliant with 100V Conductor
Spacing Guidelines per IPC-2221
• Break-Before-Make Dead-Time Prevents Shoot-through and is
adjustable up to 220ns
• Bootstrap Supply Max Voltage to 114VDC
• Wide Supply Voltage Range (8V to 14V)
• Supply Undervoltage Protection
• CMOS Compatible Input Thresholds with Hysteresis (HIP2120)
• 1.6Ω/1Ω Typical Output Pull-up/Pull-down Resistance
• On-Chip 1Ω Bootstrap Diode
Applications
• Telecom Half-Bridge DC/DC Converters
• UPS and Inverters
• Motor Drives
• Class-D Amplifiers
• Forward Converter with Active Clamp
