TP5000X-4.2-ESOP8

TP5000X is a switching buck single manganese lithium battery charge management chip. Its ESOP8 package with simple peripheral circuit, making the TP5000X is ideal for portable equipment large current charging management applications. Meanwhile, TP5000X built-in input overcurrent, undervoltage protection, over temperature protection, short circuit protection, battery temperature monitoring, reverse battery protection, shutdown OVP function due to excessive input power. TP5000X has a wide input voltage, divided into three stages Trickle pre-charge, constant current, constant voltage trickle charge the battery pre-charge current, constant current charging current adjusted through an external resistor, the maximum charging current of 2A. TP5000X switching frequency of 800kHz operating mode so that it can use smaller external components and smaller heat remains in the high current charging. TP5000X Built-power the PMOSFET, anti-intrusion circuit, so there is no need anti-intrusion perimeter protection Schottky diodes.
