ELM77xxxxxCCMOS Dual voltage detector
ELM77xxxxxC is CMOS dual voltage detector which consists of two comparator circuits watching Vdetn2 (Vdd level) and Vdetn1(Vdet input level) simultaneously and independently. This configuration enables output to maintain the state of detection even when voltage of the Vdet input level drops to 0V.
| Detection voltage range | Vdetn1(Vdet): 0.8V to 5.0V(by0.1V) Vdetn2(Vdd): 1.1V to 5.0V(by0.1V) |
|---|---|
| Low current consumption | Typ.0.6µA(Vdd=3.0V) |
| High accuracy detection voltage | ±2.0%(Vdetn1, 2>1.5V) &mlusmn;30mV(Vdetn1, 2<=1.5V) |
| High input resistance | Typ.10MΩ |
| Low temperature coefficient | Typ.±100ppm/°C |
| Output configuration | N-ch open-drain |
| Package | SOT-25 |
| Datasheet | ELM77series |
- Application
- Reset for microcomputers
