L99H01 Motor bridge driver for automotive applications Datasheet - production data Applications Wiper Power door Seat belt tensioner Seat positioning LQFP32 PowerSSO-36 Valve tronic 7x7mm Park break 2H motors Features Description Operating supply voltage 6 V to 28 V Central 2 stage charge pump The L99H01 is designed to control 4 external N-channel MOS transistors in bridge configuration 100% duty cycle for DC-motor driving in automotive applications. A Full R down to 6 V (normal level DSon free configurable current sense amplifier is MOSFETs) integrated. The integrated standard serial Control of reverse battery protection MOSFET peripheral interface (SPI) controls all outputs and provides diagnostic information. An interface pin Charge pump current limited for the thermal sensors of the external MOSFETs PWM operation up to 30 kHz is implemented. 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 Table 1.
