Rochester Electronics PMIC - Supervisors MAX6381LT30D3+T

The MAX6381LT30D3+T is a low-voltage, low-power microprocessor supervisory circuit designed to monitor power supply voltages ranging from +1.8V to +5.0V. It operates with a supply current of only 3OºA at +1.8V, making it suitable for battery-powered applications. The device features factory-set reset thresholds available from +1.58V to +4.63V in approximately 100mV increments, with a reset output that asserts when VCC falls below the set threshold and remains asserted for a minimum timeout period after VCC rises above the threshold. This part offers seven minimum reset timeout delays ranging from 1ms to 1200ms, and it includes various reset output options: active-low push-pull, active-high push-pull, and open-drain active-low. The MAX6381LT30D3+T is available in a compact 6-pin OºDFN package and is AEC-Q100 qualified, making it suitable for automotive applications. It also provides negative-going VCC transient immunity and guarantees a valid reset output state down to VCC = 1V. The operating temperature range is from -40¬8C to +125¬8C, ensuring reliability in diverse environments.
