High-Voltage Watchdog Timers with  
Adjustable Timeout Delay  
7/MAX1698  
General Description  
Features  
The MAX16997/MAX16998 are microprocessor (µP)  
supervisory circuits for high-input-voltage and low-qui-  
escent-current applications. These devices detect  
downstream circuit failures and provide switchover to  
redundant circuitry. See the Selector Guide for the dif-  
ferent versions of this product family.  
o Wide 5V to 40V Input Voltage Range  
o 18µA Quiescent Current (Typical at +125°C)  
o Capacitor-Adjustable Timeout Period for  
Watchdog and Reset  
o Windowed Watchdog Timer Options  
The MAX16997/MAX16998 family has four independent  
inputs for reset and watchdog functions. SWT and SRT  
inputs independently set the timeout periods of watch-  
dog and reset timers through external capacitors.  
RESETIN/EN monitor voltages at respective inputs. A  
resistive voltage-divider sets the reset threshold.  
(MAX16998B/D)  
o External Voltage Monitoring (RESETIN for the  
MAX16998A/B/D and EN for the MAX16997A)  
o Car Battery-Compatible EN Input  
o TTL- and CMOS-Compatible Open-Drain Outputs  
o 18V Maximum Open-Drain Reset Output Voltage  
o 28V Maximum Open-Drain Enable Output Voltage  
The MAX16998A/B/D generate two output signals,  
RESET and ENABLE. RESET asserts whenever  
RESETIN drops below its threshold voltage or when the  
watchdog timer detects a timing fault at WDI. Once  
asserted, and after all reset conditions are removed,  
o Power-On/Power-Off Reset Functionality  
RESET remains low for the reset timeout period, t  
,
RESET  
(MAX16998A/B/D Only)  
and then goes high. The MAX16997A generates one  
output signal (ENABLE) based on the voltage level at  
EN and the signal at WDI.  
o AECQ-100 Qualified  
o -40°C to +125°C Operating Temperature Range  
o Small (3mm x 3mm) µMAX Package  
o WDI Narrow Pulse Immunity  
The MAX16997A does not have a RESET output. The  
watchdog is disabled if the voltage at EN is below its  
threshold. The MAX16997A watchdog timer starts tim-  
ing when the voltage at EN becomes higher than the  
preset threshold voltage level. Each time EN rises  
above the preset threshold voltage, the initial watchdog  
timeout period is 8 times the normal watchdog timeout
