Monolithic Power Systems (MPS) EVKT-MP2797-0000/0002 Evaluation Kits

Monolithic Power Systems (MPS) EVKT-MP2797-0000/0002 Evaluation Kits are designed to demonstrate the capabilities of the MP2797, a robust battery management device. This MP2797 offers a protection solution for 7-cell to 16-cell series battery systems and Analog Front-End (AFE) monitoring. The EVKT-MP2797-0000/0002 evaluation kits feature an I2C or SPI interface with an 8-bit Cyclic Redundancy Check (CRC), integrated High-Side MOSFET (HS-FET) driver, and random cell connection tolerance. These evaluation kits are available in a package of TQFP-48 (7mm x 7mm). The EVKT-MP2796-0000/0002 evaluation kits operate at 18V to 75.2V battery pack voltage and 0V to 5V cell voltage. These evaluation kits can drive external balancing transistors and are used in automatic or manual control.
