L99H01中文资料电机桥驱动器，用于汽车应用数据手册ST规格书

描述 Description

The L99H01 is designed to control 4 externalN-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.

特性 Features

• Operating supply voltage 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
