MAXIM INTEGRATED / ANALOG DEVICES MAX6389XS44D3T Low-Voltage Reset Circuit
The MAX6389XS44D3+T is a dual low-voltage, low-power microprocessor (μP) reset circuit housed in a 4-pin SC-70 package. It monitors power supply voltages ranging from 1.8V to 5V, consuming only 3μA at 1.8V. When the supply voltage drops below the preset reset threshold, the reset output asserts and stays active for at least 280 milliseconds after the voltage recovers above the threshold. The device features an open-drain, active-low reset output and an auxiliary input for monitoring a secondary voltage. It is suitable for use in controllers, intelligent instruments, microprocessor and microcontroller power monitoring, and battery-powered equipment. Key specifications include a reset threshold voltage of 4.38V with ±2.5% accuracy, a supply voltage range of 1V to 5.5V, and operation over -40°C to 125°C. The reset output remains valid at VCC as low as 1V and has immunity to negative-going VCC transients. It also offers low power consumption of 6μA at 3.6V. Due to high market demand, lead times may be extended, and the product is exempt from discounts.
