Radiation Hardened Full Bridge
N-Channel FET Driver
The HS-4080ARH is a monolithic, high frequency, medium
voltage Full Bridge N-Channel FET Driver IC. The device
includes a TTL-level input comparator, which can be used to
facilitate the “hysteresis” and PWM modes of operation. Its
HEN (high enable) lead can force current to freewheel in the
bottom two external power MOSFETs, maintaining the upper
power MOSFETs off. The HS-4080ARH is well suited for use
in distributed DC power supplies and DC to DC converters,
since it can switch at high frequencies.
These devices can also drive medium voltage motors, and
two HS-4080ARHs can be used to drive high performance
stepper motors, since the short minimum “on-time” can
provide fine micro-stepping capability.
Short propagation delays maximize control loop crossover
frequencies and dead-times, which can be adjusted to near
zero to minimize distortion, resulting in precise control of the
driven load.
Constructed with the Intersil dielectrically isolated Rad Hard
Silicon Gate (RSG) process, these devices are immune to
Single Event Latch-up and have been specifically designed
to provide highly reliable performance in harsh radiation
environments. Complete your design with radiation
hardened MOSFETs from Intersil.
Specifications for Rad Hard QML devices are controlled
by the Defense Supply Center in Columbus (DSCC). The
SMD numbers listed here must be used when ordering.
Detailed Electrical Specifications for these devices are
contained in SMD 5962-99617. A “hot-link” is provided

HS-4080ARH Preliminary Pin Descriptions
PIN
NUMBER SYMBOL
DESCRIPTION
1 BHB B High-side Bootstrap supply. External bootstrap diode and capacitor are required. Connect cathode of boot-strap
diode and positive side of bootstrap capacitor to this pin. Internal charge pump supplies 50µA out of this pin to maintain
bootstrap supply. Internal circuitry clamps the bootstrap supply to approximately 15V.
2 HEN High-side Enable input. Logic level input that when low overrides IN+/IN- (Pins 6 and 7) to put AHO and BHO drivers
(Pins 11 and 20) in low output state. When HEN is high AHO and BHO are controlled by IN+/IN- inputs. The pin can
be driven by signal levels of 0V to 18V (no greater than VDD). An internal 100µA pull-up to VDD will hold HEN high, so
no connection is required if high-side and low-side outputs are to be controlled by IN+/IN -inputs.
3 DIS DISable input. Logic level input that when taken high sets all four outputs low. DIS high overrides all other inputs. When
DIS is taken low the outputs are controlled by the other inputs. The pin can be driven by signal levels of 0V to 18V (no
greater than VDD). An internal 100µA pull-up to VDD will hold DIS high if this pin is not driven.
4 VSS Chip negative supply, generally will be ground.
5 OUT OUTput of the input control comparator. This rail to rail output signal can be used for feedback and hysteresis.
6 IN+ Noninverting input of control comparator. This pin can only be driven by signal levels of 0V to 5.5V. If IN+ is greater
than IN- (Pin 7) then ALO and BHO are low level outputs and BLO and AHO are high level outputs. If IN+ is less than
IN- then ALO and BHO are high level outputs and BLO and AHO are low level outputs. DIS (Pin 3) high level will
override IN+/IN- control for all outputs. HEN (Pin 2) low level will override IN+/IN- control of AHO and BHO. When
switching in four quadrant mode, dead time in a half bridge leg is controlled by HDEL and LDEL (Pins 8 and 9).
7 IN- Inverting input of control comparator. This pin can only be driven by signal levels of 0V to 5.5V. See IN+ (Pin 6)
description.
8 HDEL High-side turn-on DELay. Connect resistor from this pin to VSS to set timing current that defines the turn-on delay of
both high-side drivers. The low-side drivers turn-off with no adjustable delay, so the HDEL resistor guarantees no
shoot-through by delaying the turn-on of the high-side drivers. HDEL reference voltage is approximately 5.1V.
9 LDEL Low-side turn-on DELay. Connect resistor from this pin to VSS to set timing current that defines the turn-on delay of
both low-side drivers. The high-side drivers turn-off with no adjustable delay, so the LDEL resistor guarantees no shoot-
through by delaying the turn-on of the low-side drivers. LDEL reference voltage is approximately 5.1V.
10 AHB A High-side Bootstrap supply. External bootstrap diode and capacitor are required. Connect cathode of boot-strap
diode and positive side of bootstrap capacitor to this pin. Internal charge pump supplies 30µA out of this pin to maintain
bootstrap supply. Internal circuitry clamps the bootstrap supply to approximately 15V.
11 AHO A High-side Output. Connect to gate of A High-side power MOSFET.
12 AHS A High-side Source connection. Connect to source of A High-side power MOSFET. Connect negative side of bootstrap
capacitor to this pin.
13 ALO A Low-side Output. Connect to gate of A Low-side power MOSFET.
14 ALS A Low-side Source connection. Connect to source of A Low-side power MOSFET.

16

19 BHS B High-side Source connection. Connect to source of B High-side power MOSFET. Connect negative side of bootstrap
