19-4000; Rev 1; 4/09 High-Voltage Watchdog Timers with Adjustable Timeout Delay General Description The MAX16997/MAX16998 are microprocessor (µP) supervisory circuits for high-input-voltage and low-quiescent-current applications.
These devices detect downstream circuit failures and provide switchover to redundant circuitry.
See the Selector Guide for the different versions of this product family.
The MAX16997/MAX16998 family has four independent inputs for reset and watchdog functions.
SWT and SRT inputs independently set the timeout periods of watchdog and reset timers through external capacitors.
RESETIN/EN monitor voltages at respective inputs.
A resistive voltage-divider sets the reset ...
