uP Supervisory Circuits
DESCRIPTION
The ETC705/ETC706/ETC707/ETC708 are inexpensive
microprocessor supervisory circuits that monitor power
supplies in microprocessor based systems. The circuit
functions include a watchdog timer, microprocessor
reset, power failure warning and a debounced manual
reset input.
The ETC705 and ETC706 offer a watchdog timer
function while the ETC707 and ETC708 have an active
high reset output in addition to the active low reset
output.
Supply voltage monitor levels of 4.65V and 4.4V are
available. The ETC705/ETC707 have a nominal reset
threshold level of 4.65V while the ETC706 and ETC708
have a 4.4V nominal reset threshold level. When the
supply voltage drops below the respective reset
threshold level, RESET is asserted.
FEATURES
Debounced Manual Reset Input is
TTL/CMOS Compatible
· Reset Pulse Width, 200ms
· Watchdog Timer, 1.6s (ETC705/ETC706)
· 4.4V or 4.65V Precision Voltage Monitor
· Early Power Fail Warning or Low Battery
Detect
