Description
The MP3713 is a robust battery management device, providing a complete analog front-end (AFE) monitoring and protection solution. The device can support I2C or serial peripheral interface (SPI) communication. It supports connections for 3-cell to 10-cell series battery packs, with an absolute voltage exceeding 80V on particular pins.
The MP3713 integrates two separate analog-to-digital converters (ADCs). The first ADC measures each channel’s differential cell voltages (up to 10 channels), die temperature, and 7-channel temperatures via external negative temperature coefficient (NTC) thermistors. The second ADC measures the charge/discharge current via an external current-sense resistor. The dual ADC architecture enables synchronous voltage and current measurements for cell and pack impedance monitoring.
When paired with an MPF4279x fuel gauge, the MP3713 can achieve state-of-charge (SOC) accuracy to within 2%.
The MP3713 includes high-side MOSFET (HS-FET) drivers for charge and discharge independent control. The discharge (DSG) MOSFET driver includes a configurable-scaled current 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.
The MP3713 integrates the fuse driver for severe under-voltage protection (SUVP), severe over-voltage protection (SOVP), MOSFET damage protection, and abundant self-diagnostics protection.
Internal passive balancing MOSFETs can be used to equalize mismatched cells, supporting up to 58mA. There is also an option to drive external balancing transistors (MOSFET or BJT).
The MP3713 is available in a TQFP-48 (7mmx7mm) package.
