TP5100 8.4V / 4.2V Lithium Battery Charge Management Chip QFN16-Package

TP5100 8.4V / 4.2V Lithium Battery Charge Management Chip QFN16-Package

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 is 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 lithium battery charge management IC has a wide input voltage 5 to 18 Volts, 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. Featured by Sharvi Electronics The maximum charging current of 2 Ampere. TP5100 lithium charge management IC uses the frequency of 400kHz switching mode makes it possible to use a smaller peripheral device, and still maintain a smaller amount of heat in the large current charging. TP5100 built-in power of the PMOSFET, anti-intrusion circuit, there is no need peripheral anti-intrusion protection Schottky diode.
