CXDR75300 is an integrated circuit that combines undervoltage protection and current detection comparator. The chip includes circuit units such as current detection comparator, power undervoltage comparator, voltage reference source, and timer. It is very suitable for applications such as overcurrent protection, current detection, or battery discharge management. It has the characteristics of low power consumption, simple application, and flexibility. When the power supply voltage drops below the undervoltage threshold (typical value 2.75V) for 100 milliseconds, CXDR 75300 enters an undervoltage state and outputs a high level at the OD pin and a low level at the pin. Only when the power supply voltage exceeds the undervoltage threshold of 0.33V for 100 milliseconds, the CXDR 75300 recovers from the undervoltage state and outputs a low level at the OD pin and a high level at the pin. When the voltage difference between the CSP pin of the current detection positive input terminal and the CSN pin of the current detection negative input terminal is greater than the overcurrent detection threshold (typical value of 38 millivolts) and lasts for more than 9 milliseconds, it enters an overcurrent state, and the CXDR 75300 outputs a high level at the OD pin and a low level at the pin. The undervoltage state or overcurrent state is collectively referred to as the over discharge state. The CXDR75300 is highly suitable for applications such as overcurrent protection, current detection, and discharge management of three nickel hydrogen batteries or single lithium batteries. The CXDR75300 adopts the SOT-23 package with 6 pins.
