CN1185
Description
CN1185 is a low-power four-channel voltage monitoring chip, it consumes only 7.3 microamps current, very suitable for monitoring the battery voltage. The divice contains four voltage comparators, each comparator's positive input received on-chip voltage reference.
Key Features
- Operating supply voltage range：2.7V-6V
- 7.3µA Supply Current @VCC=4V
- Guaranteed Output Valid to VCC = 1.2V
- Four-channel voltage comparator
- Open-drain output
- Start time: 15 ms (typical)
- Output can drive LED or connected with the microprocessor
- Precise Reset Threshold: 2.5%
- Comparator hysteresis can be set by two logical ports
- 60ms typical Delay to Filter out the noise
