STEF12H60数据手册集成电路（IC）的电流调节/管理规格书PDF

描述 Description

The STEF12H60 is a 60 A integrated electronic fuse optimized for monitoring the output current and the input voltage, over the 12 V DC power lines.
When connected in series to the main power rail, it is able to detect and react to overcurrent conditions. When an overload condition occurs, the device limits the output current to a safe value defined by the user.
A precise current monitor signal provides continuous information about the load current to the system controller IC.
Similarly, a precise temperature sensor generates a monitor signal that permits the system controller to keep the device power dissipation under control.
Turn-on time is programmable, which helps control the inrush current during start-up operations.
The device also embeds the undervoltage lock-out feature, self-diagnostic and absolute thermal protection.
