The PT7M78xx 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:
| Adjustable Detect Voltage Reference Voltage (V) | N/A |
|---|---|
| Ambient Temperature Range (°C) | -40 to 85 |
| Fixed Detect Voltages (V) | 2.2, 2.25, 2.32, 2.63, 2.80, 2.93, 3.08, 4, 4.38, 4.63 |
| Manual RESET | No |
| Maximum Input Voltage (V) | 5.5 |
| Minimum Operating Voltage (V) | 1 |
| Number of Channels | 1 |
| Power Fail Comparator Threshold (V) | None |
| Quiescent Current (µA) | 10 |
| RESET Output (Active High) | No |
| RESET Output (Active Low) | Yes |
| Reset Output Topology | Open-Drain |
| Reset Period (ms) | 200 |
| Typical Time Delay (µs) | N/A |
| Watchdog | No |
| Watchdog Time (s) | None |
