Description

The PT7M1233/1233A series are designed to monitor

power supplies in µ and digital systems. They

provide excellent circuit reliability and low cost by

eliminating external components and adjustments.

The devices perform a single function: assert a reset

signal whenever the V

supply voltage falls below a

preset threshold. Reset remains asserted 200ms after

has risen above the reset threshold.

PT7M1233/1233A are bidirectional output, allowing it

to monitor a pushbutton on the reset output.

Function Description

Power Monitor

A microprocessor’s (µP’s) reset input starts the µP in a known state. Whenever the µ is in an unknown state, it should be held in

reset. The supervisory circuits assert reset during power-up and prevent code execution errors during power-down or brownout

conditions.

On power-up, once Vcc reaches about 1.0V, RST is a guaranteed logic low of 0.4V or less. As Vcc rises, RST stays low. When

Vcc rises above the reset threshold V

RST

, an internal timer releases RST after about 200ms. RST asserts whenever Vcc drops

below the reset threshold, i.e. brownout condition. If brownout occurs in the middle of a previously initiated reset pulse, the pulse

continues for at least another 200ms. On power-down, once Vcc falls below the reset threshold, RST stays low and is guaranteed

to be 0.4V or less until Vcc drops below 1V.

Reset Output: Bi-direction

PT7M1233

The devices provide RST output pin for a pushbutton switch. When the devices are not in a reset cycle, it continuously monitors

the RST signal for a low going edge. If an edge is detected, the devices will debounce the switch by pulling the RST line low.

After the internal timer has expired, the devices will continue to monitor the RST line. If the line is still low, they will continue to

monitor the line looking for a rising edge. Upon detecting a release, they will force the RST line low and hold it low for 200ms.

PT7M1233A

When an out-of-tolerance condition is detected, an internal power fail signal is generated which forces reset to the active state.

When V

returns to an in-tolerance condition, the reset signal is kept in the active state for approximately 200ms to allow the

power supply and processor to stabilize. The second function of the PT7M1233A is pushbutton reset control. The PT7M1233A

debounces a pushbutton closure and will generate a 200ms reset pulse upon release.
