Single Event Radiation Hardened  
High Speed, Current Mode PWM  
Features  
• Electrically Screened to DSCC SMD # 5962-01509  
• QML Qualified per MIL-PRF-38535 Requirements  
The IS-1845ASRH is designed to be  
used in switching power supplies  
operating in current-mode. The

turns on the output. Turn-off is controlled by the current  
sense comparator and occurs when the sensed current  
reaches a peak controlled by the error amplifier.

Constructed with Intersil’s Rad Hard Silicon Gate (RSG)  
dielectrically isolated BiCMOS process, these devices are  
immune to single event latch-up and have been specifically  
designed to provide a high level of immunity to single event  
transients. All specified parameters are guaranteed and  
tested for 300krad(Si) total dose performance.  
• Low Start-up Current . . . . . . . . . . . . . . . . . . . 100µA (Typ)  
• Fast Propagation Delay . . . . . . . . . . . . . . . . . . 80ns (Typ)

Detailed Electrical Specifications for these devices are  
contained in SMD 5962-01509. A “hot-link” is provided on  
our website for downloading the SMD.  
Applications  
• Current-Mode Switching Power Supplies  
• Control of High Current FET Drivers  
• Motor Speed and Direction Control

NOTES:  
1. Grounding the Comp pin does not inhibit the output. The output  
may be inhibited by applying >1.2V to the ISENSE pin.  
2. This part should be operated with CT=3.3nF and RT=10k timing  
components only.  
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
