MAX16998 - (MAX16997 / MAX16998) High-Voltage Watchdog Timers

Download the MAX16998 datasheet PDF. This datasheet also covers the MAX16997 variant, as both devices belong to the same (max16997 / max16998) high-voltage watchdog timers family and are provided as variant models within a single manufacturer datasheet.

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.

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 threshold. The MAX16998A/B/D generate two output signals, RESET and ENABLE .
