Product details

Single-channel voltage supervisor with adjustable threshold

The MAX6457UKD3C+T is a Simple Reset/Power-On Reset supervisor from Analog Devices that monitors a single voltage rail and asserts an active-low reset signal when the supply falls below the programmed threshold. The reset timeout is 90ms minimum — the supervisor holds the reset line low for at least this duration after VCC rises above the threshold, ensuring downstream devices complete their power-up sequence before the system starts executing code. The threshold is adjustable/selectable via an external resistor divider.

Industrial temperature range and compact footprint

Housed in a 5-pin SOT-23-5 package, the footprint suits multi-rail boards where a supervisor per rail is needed.

Active production — sourcing per RFQ

Analog Devices has not announced a discontinuance or last-time-buy window for this order code. The part is ROHS3 compliant.

Frequently asked questions

Is the MAX6457UKD3C+T threshold adjustable?

The datasheet provides the formula to set the trip voltage for any desired rail.

What output type does the MAX6457UKD3C+T have?

The output is open drain or open collector. It pulls low when the reset is asserted; an external pull-up resistor to the logic supply is required for the output to reach a high level when the reset is released.

What is the reset timeout of the MAX6457UKD3C+T?

The reset timeout is 90ms minimum. After the monitored voltage rises above the threshold, the reset output remains low for at least 90ms before releasing.
