Product Details
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 watch dog and reset timers through external capacitors. RESETIN/EN monitor voltages at respective inputs. A resistive voltage-divider sets the reset threshold.
Features
♦ Wide 5V to 40V Input Voltage Range♦ 18µA Quiescent Current (Typical at +125°C)
♦ Capacitor-Adjustable Timeout Period for Watchdog and Reset
♦ Windowed Watchdog Timer Options (MAX16998B/D)
♦ External Voltage Monitoring (RESETIN for the MAX16998A/B/D and EN for the MAX16997A)
♦ Car Battery-Compatible EN Input
♦ TTL- and CMOS-Compatible Open-Drain Outputs
♦ 18V Maximum Open-Drain Reset Output Voltage
♦ 28V Maximum Open-Drain Enable Output Voltage
♦ Power-On/Power-Off Reset Functionality (MAX16998A/B/D Only)
♦ AECQ-100 Qualified
♦ -40°C to +125°C Operating Temperature Range
♦ Small (3mm x 3mm) µMAX Package
♦ WDI Narrow Pulse Immunity
