ASM705/706/707/708 and ASM813L
Low Power
μP
Supervisor Circuits
General Description
The ASM705 / 706 / 707 / 708 and ASM813L are cost
effective CMOS supervisor circuits that monitor power-
supply and battery voltage level, and μP/μC 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.
