CN1185
Overview: CN1185 is a low-power four-channel voltage detection chip that consumes only 7.3 microamps, making it ideal for detecting battery voltage. The chip contains four voltage comparators, each with a positive input connected to an internal voltage reference, allowing it to detect four different voltage sources or perform tiered detection of a single voltage source. Users can select the comparator's inversion threshold and hysteresis through logic input ports. The hysteresis eliminates comparator output instability caused by noise or interference from the detected power source. Because users can set the comparator inversion threshold and hysteresis, the CN1185 is well-suited for applications requiring rough battery level detection. For easy integration with chips operating at different voltages within a system, the CN1185 uses an open-drain output. To ensure normal system operation during power-up, the CN1185 has a built-in start-up time of 7.5 milliseconds (minimum), during which the comparator output is high-impedance. CN1185 is packaged in a 16-pin TSSOP package.
