General Description

MP5112/MP5113 is a power bank solution device which is highly integrated with switch charger, LED display cell and synchronous boost output.
The MP5112/MP5113 has two operating modes, charge mode and boost mode, to manage the system and battery power based on the state of the input.
When input power is present, the MP5112/MP5113 operates in charge mode. It automatically detects the battery voltage and charges the battery in the three phases: trickle current mode, constant current mode and constant voltage mode.
Boost will be enabled by pressing the KEY or insertion a load at standby mode when the battery voltage is higher than 3.2V.

 u Frequency for charger:1MHz
u Charge current could be regulated by the temperature, this realize the maximum charge rate, without overheat risk
u C/10 charge terminated and recharge automatically
u Terminated charge voltage : 4.2V(MP5112)/4.35V(MP5113), the accuracy is ±1%
u Regulate the charge current refer to the adapter’s ability automatically
u Boost output 5.05V with High efficiency up to 93%@1A
u Frequency for boost:1MHz
u Output current up to 1.2A
u Detect the load automatically and auto shunt down at no load condition
u Original temperature management technology for boost
u Over-current protection (OCP ), over voltage protection ( OVP ), over temperature protection ( OTP ) and short circuit protection ( SCP ) are integrated for boost
u 2 LEDs display to indicate the battery fuel gauge
u Single key for battery fuel gauge display; double key for torch; long key to shut down the boost
u Package:ESOP8/SOP8


Application

Ÿ Sub-Battery Applications
Ÿ Power-Bank Applications for Smart-Phone Tablet and Other Portable Devices
 

Features

u Low quiescent current: 75uA
u Switch charge with high efficiency up to 90%@1A
u Charge current up to 1A
