Description
The IR53H(D)420(-P2) are complete high voltage, high speed,
self-oscillating half-bridge circuits. Proprietary HVIC and latch
immune CMOS technologies, along with the HEXFET® power
MOSFET technology, enable ruggedized single package con-
struction. The front-end features a programmable oscillator
which functions similar to the CMOS 555 timer. The supply to
the control circuit has a zener clamp to simplify offline opera-
tion. The output features two HEXFETs in a half-bridge con-
figuration with an internally set deadtime designed for mini-
mum cross-conduction in the half-bridge. Propagation delays

NOTE 1:
This IC contains a zener clamp structure between V
CC
and COM which has a nominal breakdown voltage of 15.6V.
Please note that this supply pin should not be driven by a DC, low impedance power source greater than the V
CLAMP
specified in the Electrical Characteristics Section

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All volt-
age parameters are absolute voltages referenced to COM, unless stated otherwise. All currents are defined
positive into any lead. The thermal resistance and power dissipation ratings are measured under board
mounted and still air conditions.

Recommended Operating Conditions
The input/output logic timing diagram is shown in figure 1. For proper operation, the device should be used
within the recommended conditions.
NOTE 2:
Care should be taken to avoid switching conditions where the V
S
node flies inductively below ground by more than 5V.
NOTE 3:
Enough current should be supplied to the V
CC
lead of the IC to keep the internal 15.6V zener diode clamping the
voltage at this lead.
