Ordering Information
The PT7M7xxx 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-up, power-down
and brownout conditions for µP system;
2. Detecting power failure or low-battery conditions with
a 1.25V threshold detector;
3. Watchdog functions;
4. Manual reset.
Applications
• Power-supply circuitry in µP systems
Note: lead free package is available by adding E at the end of each part no. For example: PT7M7803XTE for
SOT23-3 lead free package.
Suffix: X -- Monitored Voltage
