DRV8001-Q1中文资料用于前车门控制的汽车级 40V 多功能半桥 & 高侧驱动器数据手册TI规格书

描述 Description

The DRV8001-Q1 device integrates multiple door control specific functions: driving and diagnosing motor (inductive), resistive and capacitive loads, driving a lamp or LEDs, drive MOSFETs for special loads such as heating element or electrochromic elements. These drivers include protection features for offline and active diagnostics such as under and over voltage monitors, offline open load and short-circuit diagnostics, and zone-based thermal monitoring and shutdown protection. The device features 6 integrated half-bridges (2 high-side alternate modes), 6 integrated high-side drivers, one external high-side gate driver for heater, one external high-side gate driver for electrochromic charge and one integrated low-side driver for electrochromic load discharge. Each individual driver has PWM input control configuration, sensing, diagnostics and device system protection. There is a dedicated internal programmable PWM generators for each high-side driver. Proportional current sense pin output is available for all integrated drivers
