IR2105STR is a type of integrated circuit commonly found in PMIC - Gate Drivers (Power Management and Integrated Circuits). It is a highly integrated, cost-effective and low-power consumption advanced BiCMOS technology. It is a three-state, high-side and low-side driver with an integrated delayed turn-off characteristic that allows improved system EMC performance. Additionally, the intermediate stage of this device provide an integrated delay feature for improved transient performance when driving high-current loads.

IR2105STR has a wide range of applications, from automotive and consumer electronics to industrial and telecom systems. Automotive applications primarily use the device for driving loads, such as motor drivers, screen wipes, wiper motor drivers, fan controllers and sliding roof controllers. The device is also used in consumer electronics for the driving of displays, LCD televisions, monitor backlights and even in small appliances such as remote controllers. In industrial applications, the IR2105STR is used in the control of stepping motors and vibration motors.

The IR2105STR features two independent high-side and low-side gate drivers integrated into one package. The high-side gate driver is composed of two complementary N-channel and P-channel power MOSFETs, two Schottky diodes and two integrated N-channel power MOSFETs. The low-side gate driver is composed of two complementary N-channel MOSFETs and two resistive loads, which can be used to adjust the gate impedance of the MOSFETs. The device also contains circuitry to provide a delayed turn-off characteristic. This delay feature is programmable via an external resistor and capacitor network.

The IR2105STR is designed to drive both large and small loads. It can supply peak currents of up to 5A and average currents up to 1.5A. The device features cycle-by-cycle current limiting, with a voltage-controlled PWM mode. This reduces the power dissipation and improves efficiency. The device also features a shutdown function that can be triggered by either the high-side or low-side gate driver. It provides low-noise operation, with a minimum on-state transition time of 15ns and a minimum turn-on time of 35ns.

The IR2105STR uses a standard logic pitch for both the high-side and low-side gate drivers, making it easy to integrate into a system. The device is designed to operate over a wide range of supply voltages and can function down to 4V. The device also features a thermal shutdown input, giving it a high degree of protection from over-temperature conditions.

The IR2105STR is a versatile and efficient integrated circuit, offering high-performance and strong protection in a small package. It is ideal for use in a wide range of applications, including automotive, industrial, and consumer electronics. It features an advanced BiCMOS architecture and delivers high current-to-voltage and voltage-to-current ratio. As well as the delayed turn-off function, it also provides cycle-by-cycle overcurrent protection, current-limit protection and thermal shutdown.
