MP3716 3-Cell to 18-Cell, High-Accuracy Battery Monitor and Protector with Coulomb Counting
The MP3716 is a robust battery management device, providing a complete analog front-end (AFE) monitoring and protection solution. It supports connections for 3-cell to 18-cell series battery packs, with an absolute voltage exceeding 80V on particular pins.
The MP3716 integrates two separate analog-to-digital converters (ADCs). The first ADC measures each channel’s differential cell voltages (up to 18 channels), die temperature, and 7-channel temperatures via external NTC thermistors. The second ADC measures the charge/discharge current via an external current-sense resistor.
When paired with an MPF4279x fuel gauge, the MP3716 can achieve state-of-charge (SOC) accuracy to within 2%.
The MP3716 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.
The MP3716 integrates a fuse driver for severe under-voltage protection (SUVP), severe over-voltage protection (SOVP), MOSFET damage protection, and abundant self-diagnostics protection.
For applications requiring compliance with IPC 2221B or UL 60950-1, conformal coating may be required depending on the battery pack voltage.
The MP3716 is available in a TQFP-48 (7mmx7mm) package.
