The MC34982CHFK from ON Semiconductor is a multichannel power multiplexer designed for use in automotive devices, offering control over up to 8 channels of power devices. The IC is capable of routing power for applications such as door locks, lighting, mirrors and more. The IC allows the user to rapidly switch power on and off in order to control power flow.

The MC34982CHFK is an ideal solution for automotive power distribution applications because of its wide input voltage range (2.7V to 5.5V) and internal protection features such as over-current protection, thermal shutdown and voltage regulation. The IC can switch up to 8 channels of power and controls load currents up to 200mA with a low on-state resistance of 0.55Ω.

The MC34982CHFK also features hot-swap capability, which prevents inadvertentloads from being connected or disconnected under power. Additionally, the IC can be enabled or disabled in a controllable manner by the user.

The MC34982CHFK is ideal for automotive applications that require load drivers, power distribution switches and manage load currents up to 200mA. The IC can be used in applications such as sprinklers, lighting and motors, as these applications are typically powered by low voltages and require reliable current switching.

The MC34982CHFK utilizes a variable resistor to adjust the current that flows through each MOSFET channel. This allows the user to control precisely the amount of current that flows through the MOSFET channels. In addition, the IC features guarding or semi-guarding of control pins, which helps to prevent static electricity discharges and EMI.

The MC34982CHFK also offers a power-off low power mode for higher efficiency and improved reliability. This mode allows the IC to enter a low-power standby mode and can then be woken up with a single logic signal, minimizing current consumption.

Overall, the MC34982CHFK from ON Semiconductor is a reliable, efficient and robust power multiplexer designed for automotive applications. The IC offers versatility and is ideal for use in power distribution switches, load drivers and more.
