EVAL-L99H02QF

EVAL-L99H02QF Data brief L99H02QF evaluation board Features • • • Operating supply voltage from 6 V to 28 V Central 2 stage charge pump 100 % duty cycle Full RDSon down to 6 V (normal level MOSFETs) • • • • • • • • Control of reverse battery protection MOSFET Charge pump current limited PWM operation up to 30 kHz SPI interface Current sense amplifier/free configurable Zero adjust for end of line trimming Power management: programmable free-wheeling Sensing circuitry of external MOSFETs with embedded thermal sensors Description EVAL-L99H02QF is an evaluation board designed for DC motor control in automotive applications. It is composed by a motherboard and a daughterboard on which the L99H02QF is pre-assembled. The motherboard, based on STM8A microcontroller, provides the logic section for monitoring and driving the L99H02QF assembled in the daughterboard. Product status link EVAL-L99H02QF Product summary Order code EVAL-L99H02QF Reference L99H02QF evaluation board With the aim to make the board usage and settings simpler, ST provides a dedicated user-friendly software with a Graphic User Interface (GUI). This enables the user to set L99H02QF parameters and registers, simultaneously showing real time device diagnostic information like motor evolution, free-wheeling, board temperature and much more.
