EV2632-R-01A Evaluation Board of All-in-one 3A Battery Charge and 3A Boost Discharge The Future of Analog IC Technology DESCRIPTION FEATURES The EV2632-R-01A is the evaluation board 4.65V-to-6V Operating Input Voltage Range designed to demonstrate the capabilities of Power Management Function Integrated MPS MP2632, a highly-integrated, flexible Input-Current-Limit and Input Voltage switch-mode battery charge management for a Regulation single-cell Li-ion and Li-Polymer battery used in Up to 3A Programmable Charge Current a wide range of applications. Selectable 4.45V / 4.35V / 4.2V Charge EV2632 uses two operating modescharge Voltage with 0.5% Accuracy mode and boost modeto allow management Battery Temperature Monitoring of system and battery power based on the state 4-LED for battery fuel gauge indication of the input. Programmable Timer Back-Up Protection Battery-Reverse-Leakage Blocking When input power is present, the board Reverse-Boost-Operation for Powering charges a single-cell battery with a System programmable charge current of up to 3A. Up to 94% 5V Boost Mode Efficiency 3A In the absence of an input source, the board with BATT=4.5V switches to boost mode through the PB pin to Up to 3A Programmable Output Current power the SYS pins from the battery with a Limit in Boost Mode current of up to 3A. APPLICATIONS The evaluation board provides 4-LED to achieve the voltage based fuel gauge indication Sub-battery Applications and distinguish charge mode from boost mode. Power-bank Applications for Smart-Phone, To guarantee safe operation, the EV2632 has Tablet and Other Portable Devices input-over-voltage protection, battery over- All MPS parts are lead-free, halogen free, and adhere to the RoHS voltage protection, thermal shutdown, battery- directive.
