L9375TRLF中文资料8-channel valve driver数据手册ST规格书

描述 Description

The L9375TRLF is a SPI controlled octal channel low side driver with integrated recirculation diodes.
The output duty cycle (Q5 - Q8) can be programmed individually. It is possible to program two consecutive output duty cycles per channel as well as an individual duration time for each channel actuation (all channels).

特性 Features

• Eight protected low-side drivers with diagnostics
• Four 0.16 Ω (typ) low side outputs (Q1 - Q4)
• Four 0.2 Ω (typ) PWM controlled outputs (Q5 - Q8)
• All outputs with 35 V (min) zener clamp
• Programmable output timer
• Clock monitor
• Integrated recirculation diodes (Q5-Q8 only)
• 16 bit serial peripheral interface (SPI), up to 5 MHz with diagnostics
• Battery compatible supply voltage
• Detailed load diagnostics
• Over load protection
• Open load (off-state)
• Under current
• Under voltage
• Temperature warning and shutdown
• Power or signal GND loss
• Recirculation diode loss
• Silent valve driver test

简介

L9375TRLF属于集成电路（IC）的栅极驱动器。由制造生产的L9375TRLF栅极驱动器栅极驱动器电源管理集成电路 (PMIC) 可用于提供隔离、放大、参考位移、自举或其他必要功能，这些功能可将来自电源转换应用中控制设备的信号连接到电源被控制通过的半导体设备（通常为 FET 或 IGBT）。任何特定设备提供的确切功能各不相同，但与它适合驱动的半导体配置相关。
