CN1185

CONSONANCE Low-Power Four Channel Voltage Monitoring Circuit CN1185 General 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. It can be used to monitor four different voltage source or a voltage source for monitoring different grades. Users can choose the logic input to select the comparator threshold and set the comparator hysteresis. The existence hysteresis of comparator is to eliminate the power due to interference or noise caused by the comparator output instability. Because the user can set the comparator threshold and hysteresis, making CN1185 is suitable for rough monitoring battery applications. In order to facilitate work on the same system with different voltage chip applications, CN1185 open-drain output. In order to ensure an instant s...
