Description

The PT7M6832–6840 are microprocessor (µ

supervisory circuits used to monitor low-voltage power

supplies in µ and digital systems. They provide

excellent circuit reliability and low cost by eliminating

external components and adjustments when used with

+1.2V to +1.8V powered circuits.

These devices assert a reset signal whenever the VCC

supply voltage declines below a preset threshold or

whenever manual reset (MR) is asserted. Reset remains

asserted for a fixed timeout delay after VCC has risen

above the reset threshold or when manual reset is

deasserted. Five different timeout periods are available:

70µ (voltage detector), 1.5ms, 30ms, 210ms, and 1.68s.

Reset thresholds suitable for operation with a variety of

supply voltages are available.

The PT7M6832/PT7M6835/PT7M6838 have a push-

pull active-low reset output (RESET). The PT7M6833/

PT7M6836/PT7M6839 have a push-pull active-high

reset output (RESET) and the PT7M 6834/ PT7M 6837/

PT7M 6840 have an open-drain active-low reset output

(RESET). The open-drain active-low reset output

requires a pull-up resistor that can be connected to a

voltage higher than VCC.

The PT7M6835/PT7M6836/PT7M6837 feature a

debounced manual reset input (MR), while the

PT7M6838/PT7M6839/PT7M6840 provide a RESET-

IN input allowing the user to externally adjust the reset

threshold. The reset comparator is designed to ignore

fast transients on VCC.

Low supply current of 7.5µ makes the PT7M6832–

PT7M6840 ideal for use in portable equipment. These

devices are available in 3-pin SOT23 or 4-pin SOT143

packages.
