description

GND

The TPS3836, TPS3837, TPS3838 families of

RESET

supervisory circuits provide circuit initialization

and timing supervision, primarily for DSP and

processor-based systems.

TPS3837

DBV PACKAGE

(TOP VIEW)

During power on, RESET is asserted when the

supply voltage V

Thereafter, the supervisory circuit monitors V

and keeps RESET output active as long as V

remains below the threshold voltage V . An

internal timer delays the return of the output to the

inactive state (high) to ensure proper system

becomes higher than 1.1 V.

GND

RESET

reset. The delay time starts after V

has risen

above the threshold voltage V .

When CT is connected to GND a fixed delay time of typical 10 ms is asserted. When connected to V the delay

time is typically 200 ms.

When the supply voltage drops below the threshold voltage V , the output becomes active (low) again.

All the devices of this family have a fixed-sense threshold voltage V set by an internal voltage divider.

The TPS3836 has an active-low push-pull RESET output. The TPS3837 has active-high push-pull RESET, and

TPS3838 integrates an active-low open-drain RESET output.
