These devices reduce the plexity and number of ponents 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. Features - Precision supply-voltage monitor - 4.63V (PT7M7xxx L) - 4.38V (PT7M7xxx M) - 3.08V (PT7M7xxx T) - 2.93V (PT7M7xxx S) - 2.63V (PT7M7xxx R) - 2.32V (PT7M7xxx Z) - 2.20V (PT7M7xxx Y) - 4.00V (PT7M7xxx J) - 200ms reset pulse width - Debounced CMOS-patible manual-reset input (7811, 7812, 7823, 7825, 7342-7344) - Reset Output Signal for Watchdog and Power Abnormal, Manual Reset - Reset Push-Pull output (PT7M7809,7811,7823, 7824,7825,7342,7345) - Reset Open-Drain output (PT7M7803/7343) - Voltage monitor for power-fail or low battery warning - Guaranteed RESET/RESET valid at VCC = 1.0V Applications - Power-supply circuitry in µP systems Ordering Information 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.
