描述 Description
The PT7A751X/752X/753X family microprocessor(μP) supervisory circuits are targeted toimprove reliability and accuracy of power-supplycircuitry in μP’s systems. These devices reduce thecomplexity and number of components required tomonitor power-supply and battery functions.The main functions are:1. Asserting reset output during power-up, power downand brownout conditions for μP system.2. Detecting power failure or low-batteryconditions with a 1.25V threshold detector.3. Watchdog functions (not for PT7A753x)
特性 Features
Precision supply-voltage monitor- 4.63V (PT7A7511, 7521, 7531)- 4.38V (PT7A7512, 7522, 7532)- 3.08V (PT7A7513, 7523, 7533)- 2.93V (PT7A7514, 7524, 7534)- 2.63V (PT7A7515, 7525, 7535)
200ms reset pulse width
Debounced TTL/CMOS-compatible manual reset input
Independent watchdog timer 1.6sec time-out (not available for PT7A7531 - 7535)
Reset output signal:- Active-low only (PT7A7511 - 7515)- Active-high only (PT7A7521 - 7525)- Active-high and active-low (PT7A7531 - 7535)
Voltage monitor for power-fail or low battery warning
Guaranteed RESET/RESET valid at VCC=1.2V
