The is a 1% accurate, quad voltage microprocessor supervisor in 16 pin TQFN package. This device offers independent outputs for each monitored voltage along with a reset output that asserts whenever any of the monitored voltages fall below their respective thresholds or the manual reset input is asserted. The reset output remains asserted for the reset timeout after all voltages are above their respective thresholds and the manual reset input is deasserted. The minimum reset timeout is internally set to 140ms or can be adjusted with an external capacitor. All open-drain outputs have internal 30µA pull-ups that eliminate the need for external pull-up resistors. Each output can be driven with an external voltage up to 5.5V. An additional feature is a watchdog timer that asserts RESET complementary when the watchdog timeout period 1.6s typ is exceeded. The watchdog timer can be disabled by leaving WDI unconnected.
