Product details

Supervisor IC for 3V rails — open-drain, active-low reset

The Analog Devices MAX6315US30D3+ is a simple reset/power-on reset IC that monitors a single 3V supply rail and asserts an active-low, open-drain reset output when the voltage falls below the 3V threshold. The reset output remains asserted for a minimum of 140ms after the supply recovers, providing a clean startup sequence for microprocessors, DSPs, or FPGAs. This part is a straightforward, no-frills supervisor for a 3V system where the designer needs a guaranteed reset pulse and does not require manual reset input or watchdog timer functionality.

Listed as Active on the manufacturer's lifecycle status.

140ms reset timeout — what it means for system boot

Frequently asked questions

What is the reset timeout of MAX6315US30D3+?

The reset timeout is 140ms minimum. After the monitored 3V supply rises above the threshold, the reset output stays low for at least 140ms before releasing the processor.

What is the output type and reset polarity?

The output is open-drain (or open-collector) and the reset is active low. An external pull-up resistor to the supply rail or another logic voltage is required for the output to drive a high level when not asserting reset.

What package does MAX6315US30D3+ come in?

It is supplied in a SOT-23-4 surface-mount package (also referenced as TO-253-4 or TO-253AA). The four-pin footprint is compact and widely used for supervisor ICs.
