L9950数据手册集成电路（IC）的电源管理-专用规格书PDF

描述 Description

The L9950 and L9950XP are microcontroller driven multifunctional door actuator driver for automotive applications.Up to five DC motors and five grounded resistive loads can be driven with six half bridges and five highside drivers. The integrated standard serial peripheral interface (SPI) controls all operation modes (forward, reverse, brake and high impedance). All diagnostic informations are available via SPI.

特性 Features

• One full bridge for 6A load (Ron=150 mΩ )
• Two half bridges for 3A load (Ron=300 mΩ )
• Two half bridges for 1.5A load (Ron=800 mΩ )
• One highside driver for 6A load (Ron=100 mΩ )
• Four highside drivers for 1.5 A load (Ron=800 mΩ )
• Programmable softstart function to drive loads with higher inrush currents (i.e. current >6 A,>3 A,>1.5 A)
• Very low current consumption in standby mode (IS
• Current monitor output for 300 mΩ, 150 mΩ and 100 m highside drivers
• All outputs over temperature protected
• Open load diagnostic for all outputs
• Overload diagnostic for all outputs
• Seperated half bridges for door lock motor
• PWM control of all outputs
• Charge pump output for reverse polarity protection
