CXDR75200 is an integrated circuit that combines undervoltage protection and current detection comparator. The chip contains a power sourceCircuit units such as flow detection comparator, power undervoltage comparator, voltage reference source, and timer are very suitable for overcurrent detectionApplications such as protection, current detection, or battery discharge management have the characteristics of low power consumption, simple application, and flexibility. When the power supply voltage drops below the undervoltage threshold (typical value 1.808V) for 100 milliseconds, CXDR75200 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 by 0.21V or more and lasts for 100 milliseconds, CXDR75200 recovers from the undervoltage state at the OD pinOutput low level and output high level at the OD 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 CXDR75200 outputs a high level on the OD pin and a low level on the OD pin. The undervoltage state or overcurrent state is collectively referred to as the over discharge state. The CXDR75200 is highly suitable for applications such as overcurrent protection, current detection, and discharge management of two nickel hydrogen batteries or a single lithium titanate battery. The CXDR75200 adopts the SOT-23 package with 6 pins.
