ASM813L General Description
The ASM705 / 706 / 707 / 708 and AS813L are cost effective CMOS supervisor circuits that monitors 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 4.65V (ASM705/707/813L) or 4.40V (ASM706/708). For 3V power supply applications, refer to the ASM705P/R/S/T data sheet. In addition, the ASM705/706/813L feature a 1.6 second watchdog timer. The ASM707/708 have both active-HIGH and active-LOW reset outputs but no watchdog function. The ASM813L has the same pin-out and functions as the ASM705 but has an active-HIGH reset output.A versatile power-fail circuit has a 1.25V threshold, useful in low battery detection and for monitoring non-5V supplies. All devices have a manual reset (MR) input. The watchdog timer output will trigger a reset if connected to MR.
All devices are available in 8-pin DIP, SO and MicroSO packages.
