HIP2101IR is a integrated low RDS(on) gate driver part of Richtek RK41 series for power semiconductor. With 3A peak drive current and fast propagation delay, it can drive N-channel, P-channel as well as low side MOSFETs, IGBTs and other power switches. HIP2101IR belongs to PMIC (power management integrated circuit) gate driver type, which is designed for portable or consumer electronics.

HIP2101IR applies to the power management applications of consumer electronics, where the minimum effort approach is taken to reduce the power dissipation and the board space. It provides two output controls for N-channel MOSFETs and one output control for P-channel MOSFETs which accepted various combinations of external control signals. With the help of HIP2101IR, the device with the high current capacity can be driven even in small spaces.

The working principle of HIP2101IR includes an open drain output with internal charge pump, which delivers high drive current in a small form factor. The input logic voltage range covers wide range of voltage, including 3.3V and 5V, making it compatible with variety of controllers. It features low gate charge and fast propagation delay, exceeding the current switching requirement of most power management applications. It is designed to achieve the maximum release current with a low gate bias voltage, providing maximum efficient power control to highly power sources.

HIP2101IR has a number of integrated protection functions that safeguard the system, such as power on reset (POR), under voltage lockout (UVLO) and short-circuit protection (SCP). Each output has an individual short-circuit protection to save the external MOSFET or other power devices. The power on reset (POR) also protects the system when the input voltage is lower than the device\'s operating voltage.

In conclusion, HIP2101IR is an ideal device for power management applications with its integrated low RDS(on) gate driver, 3A peak drive current, fast propagation delay, wide input logic voltage range and various integrated protection functions. It is a highly efficient gate driver and provides maximum efficient power control to highly power sources.
