EV3716-0000/0002-FP-00B 3-Cell to 18-Cell, High-Accuracy I2C/SPI Monitor and Protector with Coulomb Counting Evaluation Board
The EV3716-0000-FP-00B and EV3716-0002-FP-00B evaluation boards are designed to demonstrate the capabilities of the MP3716, a complete analog front-end (AFE) monitoring and protection IC. The MP3716 supports 3-cell to 18-cell series battery packs with outstanding voltage and current measurement accuracy, as well as a complete set of protection features.
The MP3716 measures each cell’s voltage and synchronously measures the charge/discharge current and Coulomb counting via an external current-sense (CS) resistor. The device includes high-side MOSFET (HS-FET) drivers for charge and discharge control. It measures the die temperature and cell temperature via 7 negative temperature coefficient (NTC) thermistor inputs. The MP3716 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 a configurable soft start (SS) that provides a 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.
These evaluation boards combine the MP3716 with power MOSFETs and a current-sense resistor 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 EV3716-0000-FP-00B and EV3716-0002-FP-00B are fully assembled and tested evaluation boards. The MP3716 is available in a TQFP-48 (7mmx7mm) package.
