Radiation Hardened Full Bridge N-Channel FET Driver
HS-4080ARH, HS-4080AEH
Features
The HS-4080ARH, 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-4080ARH,
HS-4080AEH is well suited for use in distributed DC power
supplies and DC/DC converters, since it can switch at high
frequencies.
• Electrically Screened to SMD # 5962-99617
• QML Qualified per MIL-PRF-38535 Requirements
• Radiation Environment
- Gamma Dose . . . . . . . . . . . . . . . . . . . . . 300kRAD(Si) (Max)
- Latch-up Immune RSG DI Process
• Drives N-Channel FET Full Bridge Including High-Side Chop
Capability
• Bootstrap Supply Max Voltage to 95V
• TTL Comparator Input Levels
DC
These devices can also drive medium voltage motors, and two
HS-4080ARH, HS-4080AEHs can be used to drive high
performance stepper motors, since the short minimum
“on-time” can provide fine micro-stepping capability.
• Drives 1000pF Load with Rise and Fall Times of 50ns
• User-Programmable Dead Time
• Charge-Pump and Bootstrap Maintain Upper Bias Supplies
• DIS (Disable) Pin Pulls Gates Low
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.
• Operates From Single Supply . . . . . . . . . . . . . . . . . 12V to 18V
• Low Power Consumption
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.
• Undervoltage Protection
Applications
• Full Bridge Power Supplies
• PWM Motion Control
