The PT7M62xx serials of ultra-low-power voltage detectors monitor battery, power-supply and system voltages. Each circuit includes a precision bandgap reference, a comparator, internally trimmed resistor networks that set specified trip thresholds, and an internal 5% threshold hysteresis circuit. Output is asserted when VCC rises above VTH+ (VTH+ = VTH-×1.05) and remains asserted until VCC falls below the internal VTH-. These devices provide excellent circuit reliability and low cost by eliminating external components and adjustments when monitoring nominal system voltages from +1.8V to +5V in 100mV increments. The series are voltage detectors with a propagation delay of 20μs(VCC rise).
The family is available with three output stage options:
| Adjustable Detect Voltage Reference Voltage (V) | N/A |

| Ambient Temperature Range (°C) | -40 to 85 |
| Fixed Detect Voltages (V) | 1.8 to 5 |
| Manual RESET | No |
| Maximum Input Voltage (V) | 5.5 |
| Minimum Operating Voltage (V) | 1.2 |
| Number of Channels | 1 |
| Power Fail Comparator Threshold (V) | None |
| Quiescent Current (µA) | 1 |
| RESET Output (Active High) | No |
| RESET Output (Active Low) | Yes |
| Reset Output Topology | Push-Pull |
| Reset Period (ms) | 0.2 |
| Typical Time Delay (µs) | 0.05 |
| Watchdog | No |
| Watchdog Time (s) | None |
