Product Overview
STEVAL-L99MH98 is a L99MH98 configurable octal half-bridge pre-driver board. This is a low-cost tool designed to evaluate the L99MH98, a smart power device designed by STMicroelectronics in a VFQFN48L package with an exposed pad. The L99MH98 is an integrated octal half-bridge pre-driver dedicated to controlling up to sixteen N-channel MOSFETs. It is intended for DC motor control applications such as automotive power seat control or other applications. A 24-bit SPI is used for configuring and controlling the eight half-bridges or four H-bridges. SPI status registers provide high-level diagnostic information such as supply voltage monitoring, charge pump voltage monitoring, temperature warning, and overtemperature shutdown. Each gate driver independently monitors its external MOSFET drain-source voltage for fault conditions. The L99MH98 supports indirect current measurement on external MOSFETs, allowing cost savings and lower system complexity, avoiding the usage of shunt resistors.
- Operating input voltage: VDH 6V to 28V, Vdd 5V/3.3V
- Octal half-bridge, or quad H-bridge, pre-driver
- SPI communication interface for control and diagnostics
- Programmable gate current up to 120mA
- Fully configurable half-bridge driver in case of fault occurrence
- Evaluation board design with optimized bill of materials
- Vds monitoring, three PWM inputs
- Drain-source monitoring for short circuit detection
- High-side and low-side PWM capable, configurable overvoltage threshold
- L99MH98 hosted in VFQFPN48L package and 4-layer 200x100mm PCB
