NCV7755中文资料Octal High-Side Driver that can be controlled via SPI or direct drive inputs.数据手册ONSEMI规格书

描述 Description

The NCV7755 is an automotivegrade integrated driver with eight high-side switches. The device provides drive capability up to 700mA per channel and is protected for overload and over temperature conditions. All channels have integrated output clamps for switching inductive loads, multiple start pulses for bulbs, and can be mapped to two internal PWM generators for LED loads. The output control and diagnostics reporting is via SPI. Additionally, INx pins can be mapped to any of the outputs for direct drive.

特性 Features
