ISL73321SEH Datasheet | Intersil

features precision input parators with an input threshold voltage of 600m V ±1.5% for the highest possible accuracy when monitoring the power supply voltages. The ISL70321SEH and ISL73321SEH are offered in an 18 Ld 10mmx12mm CDFP package or die form and are fully specified across the military ambient temperature range of -55°C to +125°C. With minimal external ponent count, precision voltage monitoring, and SET mitigation, the ISL70321SEH and ISL73321SEH are the ideal choice to control many of today’s highly dense power systems in high reliability applications. Applications - Power sequencing for multi-rail devices such as FPGAs, DSPs, and munications ICs - Power management of high-density distributed power systems and RF applications Features - Wide operating voltage range, 3V to 13.2V - Single resistor sets the rising and falling delay - Power-off POLs in reverse order or simultaneously - Precision voltage monitoring - 600m V ±1.5% threshold voltage over temperature and radiation - Full military temperature range operation - TA = -55°C to +125°C - TJ = -55°C to +150°C - Radiation acceptance testing - ISL70321SEH - High Dose Rate (HDR) (50-300rad(Si)/s): 100krad(Si) - Low Lose Rate (LDR) (0.01rad(Si)/s): 75krad(Si) - Radiation acceptance testing - ISL73321SEH - Low Lose Rate (LDR) (0.01rad(Si)/s): 75krad(Si) - SEE Hardness (Review SEE Report for details) - No SEB/SEL LETTH, VDD = 14.7V: 86Me V- cm2/mg - SET, SEFI free at LET 20Me V- cm2/mg - Electrically screened to DLA SMD 5962-17225 FN8942 Rev.3.0 Jul 30, 2021 Page 1 of 25 © 2017 Renesas Electronics ISL70321SEH, ISL73321SEH VO4 POL-4 5V VO3 POL-3 5V VO2 POL-2 5V...
