Description
The Q5312I-3S2 is a voltage detector IC in the R3111 Series. It is designed with high detector threshold accuracy and ultra-low supply current, making it suitable for system reset applications. This IC includes a voltage reference unit, comparator, resistor for detector threshold setting, output driver, and hysteresis circuit. The detector threshold is internally fixed with high accuracy and does not require adjustment. It is available in two output types: Nch open drain and CMOS.
Specifications and features
- Ultra-low supply current: TYP.0.8µA (VDD=1.5V)
- Wide range of operating voltage: 0.7 to 10.0V(Topt=25°C)
- Stepwise setting of detector threshold with a step of 0.1V in the range of 0.9V to 6.0V
- High accuracy detector threshold: ±2.0%
- Low temperature-drift coefficient of detector threshold: TYP. ±100ppm/°C
- Two output types: Nch open drain and CMOS
- Available in four types of packages: TO-92, SOT-89(Mini-power Mold), SOT-23-5 (Mini Mold), SC-82AB
