PMIC – Gate Drivers are a type of semiconductor device that furnishes the necessary voltage/current characteristics and signals to turn on/off and control the operation of power MOSFETs (Metal Oxide Semiconductor Field Effect Transistor). The 1SD418F2-CM1200HC-50H is a gate driver integrated circuit designed especially for the drive of high-current MOSFETs in various applications. It contains two output drivers with a static output current of up to 3A, and a high operating frequency of up to 1MHz.

The 1SD418F2-CM1200HC-50H is used for the purpose of driving high-current MOSFETs or IGBTs in various applications. Examples of the applications range from motor control, industrial inverter drives, general power management, automotive powertrain, DC/DC converter, electronic ballast and AC/DC converter. In addition, this gate driver integrated circuit has anti-cross conduction protection and over-current protection functions.

In terms of working principle, the 1SD418F2-CM1200HC-50H gate driver integrated circuit uses two outputs, with one output being the signal input, which is referred to as the control voltage. The other output is the power output, which is referred to as the source voltage. The source voltage is connected directly to the MOSFET. The control voltage is connected to the gate of the MOSFET. When the voltage on the control voltage input is increased, it will raise the voltage applied to the gate of the MOSFET, causing the MOSFET to conduct current to the drain. When the voltage on the control voltage is decreased, it will decrease the voltage applied to the gate of the MOSFET, causing the MOSFET to stop conducting current to the drain.

The 1SD418F2-CM1200HC-50H incorporates two functions – Anti-Cross Conduction Protection and Over-Current Protection. The Anti-Cross Conduction Protection prevents the undesirable flow of current between the two output channels. The Over-Current Protection prevents any current abuse on the output channel by limiting the maximum current. The integrated circuit also provides a fast turn-on/off feature, allowing the MOSFET to be turned on/off at higher speed.

The input voltage specified for operation is between 7V and 16V. The static current of the two output drivers are as follows: 3A (1SD628F3) in continuous mode and 6A (1SD628F2) in pulsed mode. The maximum switching frequency of the output drivers is 1MHz, with the propagation delay being less than 3ns.

In summary, the 1SD418F2-CM1200HC-50H is a gate driver integrated circuit that is used for the purpose of driving high-current MOSFETs or IGBTs in various applications. In addition, the integrated circuit has two functions – Anti-Cross Conduction Protection and Over-Current Protection. The input voltage specified for operation is between 7V and 16V and the static current of the two output drivers are as follows: 3A (1SD628F3) in continuous mode and 6A (1SD628F2) in pulsed mode.
