The CXPR7134A is a protection IC which includes highaccuracy voltage detector and current detector to provide Over-Voltage (OV), Under-Voltage (UV), Over-Current (OC), Short-Circuit (SC), OverTemperature (OT), Under-Temperature (UT) protection for 5-series Li-ion/polymer battery pack used in power-tools, notebook PC applications etc. The CXPR7134A provides a specific CTRL pin to control both charge and discharge FET. When CTRL is floating, the CXPR7134A will enter standby state to save power consumption. Under standby state, discharge FET is turned off while charge FET is turned on. When CTRL is tied to VCC pin, the CXPR7134A works in normal state, however, both charge and discharge FET are turned off. When CTRL is tied to VSS pin, the CXPR7134Aworks in normal state, the state of charge and discharge FET are decided according to safety events. The CXPR7134Aintegrates FET driver. The CXPR7134Acan drive the N-type charge FET and N-type discharge FET at the PACK- side directly. The CXPR7134Aconsumes less than 30uA in normal state from VCC, and it reduces to less than 3uA in standby state and less than 1uA in power-down state. Furthermore, the CXPR7134Acan be powered from a switched supply, providing a technique to reduce battery stack current draw to zero. This device is packaged in a 16-pin TSSOP package.
