General Description
The ASM706P/R/S/T/J and ASM708R/S/T/J are cost effective CMOS supervisor circuits that monitor power-supply and battery voltage level, and P/C operation. The family offers several functional options. Each device generates a reset signal during power-up, power-down and during brownout conditions. A reset is generated when the supply drops below 2.63V (ASM706P/R, ASM708R), 2.93V (ASM706S, ASM708S), 3.08V (ASM706T, ASM708T) or 4.00 (ASM706J, ASM708J). In addition, the ASM706P/R/S/T/J feature a 1.6 second watchdog timer. The watchdog timer output will trigger a reset if connected to MR. Floating the WDI input pin disables the watchdog timer. The ASM708R/S/T/J have both active-HIGH and active-LOW reset outputs but no watchdog function. The ASM706P has the same pin-out and fu……
