Rev 6.00
May 27, 2015 Radiation Hardened Full Bridge N-Channel FET Driver
The HS-4080AEH 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-4080AEH is well suited for use in
distributed DC power supplies and DC/DC converters, since it
can switch at high frequencies.
This device can also drive medium voltage motors and two
HS-4080AEHs 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. Features Electrically screened to SMD # 5962-99617 QML qualified per MIL-PRF-38535 requirements Radiation environment
