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

DESCRIPTION
Positive supply voltage for lower gate driver. 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.

2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil
Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
3. “B” package option has alternate pin assignments for compliance with 100V Conductor Spacing Guidelines per IPC-2221. Note that Pin 2 is omitted
for additional spacing.
4. For Moisture Sensitivity Level (MSL), please see device information page for HIP2120, HIP2121. For more information on MSL please see tech brief
TB363.
