DATASHEET  
Dual, Noninverting Power MOSFET Radiation Hardened  
Drivers  
HS-4424DRH  
Features  
The radiation hardened HS-4424 family are noninverting, dual,  
monolithic high-speed MOSFET drivers designed to convert low  
voltage control input signals into higher voltage, high current  
outputs. The HS-4424DRH is fully tested across the 8V to 18V  
operating range.  
• Electrically screened to DLA SMD# 5962-99560  
• QML qualified per MIL-PRF-38535 requirements  
• Latch-up immune  
• Radiation environment  
- High dose rate (50-300rad(Si)/s). . . . . . . . . . . 300krad(Si)  
The inputs of these devices can be directly driven by the  
HS-1825ARH PWM device or by our ACS/ACTS and HCS/HCTS  
type logic devices. The fast rise times and high current outputs  
allow very quick control of high gate capacitance power  
MOSFETs in high frequency applications.  
• IPEAK. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . >2A (min)  
• Matched rise and fall times (CL = 4300pF). . . . . . . 75ns (max)  
• Low voltage lockout feature . . . . . . . . . . . . . . . . . . . . . . . . <8V  
• Wide supply voltage range . . . . . . . . . . . . . . . . . . . . 8V to 18V  
The high current outputs minimize power losses in MOSFETs by  
rapidly charging and discharging the gate capacitance. The  
output stage incorporates a low voltage lockout circuit that  
puts the outputs into a three-state mode when the supply  
voltage is below its Undervoltage Lockout (UVLO) threshold  
voltage.  
• Propagation delay . . . . . . . . . . . . . . . . . . . . . . . . .250ns (max)  
• Consistent delay times with VCC changes  
• Low power consumption  
- 40mW with inputs high  
- 20mW with inputs low  
Constructed with Intersil’s dielectrically isolated Rad Hard  
Silicon Gate (RSG) BiCMOS process, these devices are immune  
to single event latch-up and have been specifically designed to  
provide highly reliable performance in harsh radiation  
environments.  
• Low equivalent input capacitance . . . . . . . . . . . . . 3.2pF (typ)  
• ESD protected. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . >4kV  
Applications  
• Switching power supplies  
• DC/DC converters
