Low Power mP Supervisor
Circuits
Description
The ASM705 / 706 / 707 / 708 and ASM813L are cost effective
CMOS supervisor circuits that monitor power−supply and battery
voltage level, and mP/mC 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 4.65 V
(ASM705/707/813L) or 4.40 V (ASM706/708). For 3 V 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 1.25 V threshold, useful in low
battery detection and for monitoring non−5 V 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.
