Description
TP5100 is a step-down switching double 8.4V / 4.2V single lithium battery charge management chip. QFN16 ultra small package with its simple external circuit, so that the large current charging management application TP5100 ideal for portable devices. Meanwhile, TP5100 built-in input overcurrent, undervoltage protection, over temperature protection, short circuit protection, battery temperature monitoring, reverse battery protection. TP5100 having a wide input voltage 5V-18V, the battery trickle charging into pre-charge, constant current, constant-voltage three phase, pre-charge current trickle charge current is adjusted through an external resistor, the maximum charging current of 2A.
