The MAX16136, a low voltage, ±1% accurate window-detector supervisor circuit monitors a single system supply voltage and the integrity of code execution by a microprocessor or microcontroller. This device features an active-low, open-drain output that asserts whenever the monitored supply rail falls outside of the factory-trimmed undervoltage/overvoltage window threshold. The reset output remain asserted for the programmed reset timeout period after the monitored supply voltage falls within the undervoltage/overvoltage window threshold.
The MAX16136 offers factory-trimmed voltage thresholds from 0.5V to 5V in approximately 20mV increment. A variety of factory trimmed undervoltage/overvoltage thresholds from ±4% to ±11% are available to accommodate different supply voltages and tolerances.
A window-watchdog timer circuit monitors microprocessor or microcontroller activity. During normal operation, the microprocessor or microcontroller must repeatedly toggle the watchdog input (WDI) low within the fast watchdog timeout (tWD_F) and slow watchdog timeout (tWD_S). If the microcontroller or microprocessor does not toggle WDI within the window-timeout period, the supervisor asserts the watchdog output (active-low WDO) to signal that the system is not executing code as expected. The watchdog output pulse can be used to reset the microprocessor or micro controller, or it may be used to interrupt the system to warn of execution errors.
In addition, the MAX16136 features an overvoltage fault output (active-low OV) that latches low when the monitored rail exceeds the overvoltage threshold. The latched output can be cleared by pulling active-low CLR low.
The MAX16136 is available in a small, 2mm x 2mm, 8-pin TDFN side-wettable package with exposed pad and operates over the automotive temperature range of -40°C to +125°C.
