• 200ms reset pulse width

The PT7A751X/752X/753X family microprocessor

(µP) supervisory circuits are targeted to improve

reliability and accuracy of power-supply circuitry in

µP systems. These devices reduce the complexity and

number of components required to monitor power-

supply and battery functions.

The main functions are:

1. Asserting reset output during power-µp, power-

down and brownout conditions for µP system;

2. Detecting power failure or low-battery conditions

with a 1.25V threshold detector;

• Debounced TTL/CMOS-compatible manual-

reset input

• Independent watchdog timer 1.6sec time-out (not

available for PT7A7531 - 7537)

3. Watchdog functions (not for PT7A753x).

• Reset output signal:

- Active-low only (PT7A7511 - 7517)

- Active-high only (PT7A7521 - 7527)

- Active-high and active-low (PT7A7531 - 7537)

• Voltage monitor for power-fail or low battery warning

• Guaranteed RESET/RESET valid at V_CC= 1.2V

Applications

• Power-supply circuitry in µP systems
