Product Summary
The ST890CDR is a low voltage, P-Channel MOSFET power switch intended for high side load switching applications. Internal current limiting circuitry protects the input supply against overload. Thermal overload protection limits power dissipation and junction temperatures. The ST890CDR maxmimum current limits is 1.2A. The current limit through the switch is programed with a resistor from SET to groung. The ST890CDR is available in SO-8 package. Main applications are: PCMCIA slots, Access bus slots, Portable equipment.
Parametrics
ST890CDR absolute maximum ratings: (1)VI Supply Voltage: -0.5 to 6 V; (2)VON, VFAULT Power DMOS Drain to Source Voltage: -0.5 to 6 V; (3)VSET, VO Logic Input Voltage: -0.5 to (VIN + 0.5)V; (4)IDS Maximum Continuous Switching Current : 1.5 A; (5)Tstg Storage Temperature Range: -65 to +150 °C; (6)Top Operating Junction Temperature Range (C series)0 to +70°C, (B series)-40 to +85°C.
