Description

TP5000 aswitching buck single manganese lithium battery / battery chargemanagement chip. Its QFN16 ultra-compact package with simple peripheralcircuit,making the TP5000 idealfor portable equipment large charging managementapplications. Meanwhile,TP5000 built-in input overcurrent, undervoltageprotection, overtemperature protection, shortcircuit protection, battery temperature monitoring, reversebattery protection.

TP5000 has a wideinputvoltage, dividedinto threestages Trickle pre-charge, constantcurrent,constantvoltage trickle chargethebattery pre-chargecurrent, constantcurrent chargingcurrent adjusted throughanexternal resistor, the maximum chargingcurrent of 2A. TP5000 switching frequencyof 800kHz operatingmode sothatit can use smaller externalcomponents and smaller heat remains in the highcurrentcharging. TP5000 Built-power the PMOSFET, anti-intrusion circuit, sothereisnoneed anti-intrusion perimeterprotection Schottkydiodes. TP5000 constantcurrent function canalsobe used dry batteries in 2 strings of lithiumbatteriesor string input,constantcurrent drive 0.5-7W white LED.
