Low-side Gate Driver IC for IGBTs and MOSFETs

SSC4S701 from Sanken Electric is a single channel low-side gate driver, and drives a power transistor such as an IGBT and a power MOSFET. The IC has the undervoltage lockout for power supply and the overcurrent protection.

When these protections are activated, the IC outputs the fault signal whose width is adjustable by an external capacitor.

Anticipated applications include inverter air conditioners, refrigerators, industrial equipment, servers, etc. Shown above is a PFC circuit example using the SSC4S701. The device has an operating temperature range of -40 to +100 °C. The IC is provided in the compact and low profile SOIC8 package.

The rated supply voltage (Vcc) is 24V (the recommended value is 15V). The output source current (peak) is -0.8A, and the output sink current (peak) is 1.75A.
