STMicroelectronics EVL9965P-N/EVL99BM2P-FN Promotional Boards

Introduction

The STMicroelectronics EVL9965P-N and EVL99BM2P-FN promotional boards are evaluation platforms designed to help engineers assess the L9965P and L99BM2P devices in automotive battery-management and energy-storage designs. They provide a practical hardware environment for testing power conversion, reserve-energy functions, communication, and safety-related switching concepts.

Part Description

These boards combine several functions commonly required in automotive energy-storage subsystems. The platform includes a boost converter for generating elevated supply rails, energy-reserve capacitors for maintaining power during transient supply interruptions, and a simulated pyro-fuse capability for evaluating safety-disconnection behavior.

Additional integrated features include an onboard low-dropout regulator (LDO), CAN communication support, and MCU interface options. Together, these capabilities allow developers to investigate device behavior, evaluate control strategies, and prototype interfaces without designing a complete test board from the ground up.

As promotional and evaluation boards, the EVL9965P-N and EVL99BM2P-FN are especially useful during early development, validation, and demonstration stages of automotive electronic systems.
