What this battery backup supervisor does on the board
The reset output is push-pull totem pole, so it drives the downstream microcontroller or logic reset input directly without an external pull-up resistor.
No official successor or drop-in replacement is listed on the lifecycle record, so any replacement will require a board respin or a validated cross from a different supervisor family. Sourcing is limited to independent distribution and surplus channels — we can quote against your BOM quantity and confirm availability at the time of the RFQ, but there is no factory pipeline to draw from.
Package and temperature grade at a glance
Housed in a 14-TSSOP package (4.40 mm width), surface-mount only, with a 0.65 mm pitch that routes cleanly on a two-layer board for this simple supervisor function.
