The EV3713-0000-FP-00A and EV3713-0002-FP-00A evaluation boards are designed to demonstrate the capabilities of the MP3713, a complete analog front-end (AFE) monitoring and protection IC. The MP3713 supports 3-cell to 10-cell series battery packs with outstanding voltage and current measurement accuracy, as well as a complete set of protection features.

The MP3713 measures each cell’s voltage and synchronously measures the charge/discharge current and Coulomb counting via an external current-sense (CS) resistor (R_CS). The MP3713 includes high-side MOSFET (HS-FET) drivers for charge and discharge control. It measures the die temperature and cell temperature via 7 NTC thermistor inputs. The MP3713 contains internal passive-balancing MOSFETs capable of driving up to 58mA, and is also capable of driving external balancing transistors for a higher current.

The discharge (DSG) MOSFET driver includes configurable soft start (SS) for controlled turn-on, eliminating the need for an external pre-charge circuit. The MOSFET drivers also incorporate over-current protection (OCP), short-circuit protection (SCP), battery under-voltage protection (UVP), battery over-voltage protection (OVP), and high/low-temperature protection. All of these protections have configurable thresholds.

This evaluation board combines the MP3713 with power MOSFETs and R_CS to support up to 70A of charge/discharge current. The board also includes placeholders to add external MOSFETs for a higher balancing current, if needed.

The EV3713-0000/0002-FP-00A are fully assembled and tested evaluation boards. The MP3713 is available in a TQFP-48 (7mmx7mm) package.
