Working Principle

The IRL6372TRPBF is a dual logic level gate drive with two independent output stages, one low side and one high side. It has two channels with outputs which can be independently controlled by the inputs of the dual channel gate drive. The high side output stage consists of a full bridge of two N-channel and two P-channel MOSFETs in the same package. The low side output stage consists of two N-channel MOSFETs and one common source P-channel MOSFET.

The IRL6372TRPBF has a built-in dead time feature. The high side and low side switches have a 0 to 200 nanosecond of dead time between them, meaning that the drive maintains the correct switching sequence and ensures correct in-line operation. This feature helps to prevent shoot-through currents and reduces losses.The device features active current protection (ISL) which helps prevent short circuit current. The current setting is adjustable, allowing precise current setting.

The IRL6372TRPBF has an integrated high and low side level shift circuit which helps to reduce magnitude of gate turn-on voltage and turn-off current. This helps to reduce switching losses and also offers low gate drive losses. The device also has a bootstrap diode circuit which helps to reduce the voltage drop.

The IRL6372TRPBF is a low cost, integrated, power MOSFET driver for bidirectional motor control applications, enabling fast level change between high and low driver signals. It features fast switching speed of high and low side MOSFETs and IGBTs, and also low gate charge and improved EMI performance for an optimized solution for bridge and three phase motor control applications.
