The TPS2553-Q1 power-distribution switch is intended for applications where precision current limiting is required or heavy capacitive loads and short circuits are encountered. It provides up to 1.5 A of continuous load current. This device offers a programmable current-limit threshold between 75 mA and 1.7 A (typical) via an external resistor. Current-limit accuracy as tight as ±6% can be achieved at the higher current-limit settings. The power-switch rise and fall times are controlled to minimize current surges during turn on and off.

The TPS2553-Q1 device limits the output current to a safe level by using a constant-current mode when the output load exceeds the current-limit threshold. An internal reverse-voltage comparator disables the power switch when the output voltage is driven higher than the input to protect devices on the input side of the switch. The FAULT output asserts low during overcurrent and reverse-voltage conditions.

TIDA-00271 — 用于远程摄像头和雷达模块中的 ADAS 传感器互连参考设计板

ADAS 传感器互连板专为需要将摄像头、激光雷达或雷达模块等远程传感器连接至中央处理 ECU 的应用而设计。该板支持最多 3 个同轴数据输入和 1 个 LVDS 双绞线数据输入，并配备 3 个 FMC 电缆和 1 个板对板连接器，用于向处理 ECU 传输数据。  通过同轴电缆连接器（SMB 标准）连接的摄像头或其他传感器模块，可直接通过同轴电缆（同轴供电）从互连板获取电源。由于所有板载 IC 均采用独立的完整供电方案，并支持同轴供电，因此可将单个汽车电池或类似的宽电压电源直接连接至 ADAS 传感器互连板上的电源连接器。板载 uC 和 LIN 接口能控制和配置互连板且支持即插即用操作。
