Description
The L99H01 is designed to control 4 external
N-channel MOS transistors in bridge configuration
for DC-motor driving in automotive applications. A
free configurable current sense amplifier is
integrated. The integrated standard serial
peripheral interface (SPI) controls all outputs and
provides diagnostic information. An interface pin
for the thermal sensors of the external MOSFETs
is implemented.
