IR2132SPBF is a double-channel high and low-side specific gate driver IC (integrated circuit) from International Rectifiers\'s automotive series. It is part of Power Management Integrated Circuits (PMICs), particularly gate drivers. It is a SOP-8 packaged device intended for automotive applications.

Gate drivers are essential components of powering schemes and they serve as an important link between the high-side and low-side switches. IR2132SPBF can drive a wide range of NMOS and PMOS high or low side switches, such as IGBTs, MOSFETs, etc., which makes them ideal for powering applications in the automotive industry. The IC is designed to keep the current limited in an abnormal mode. The device also provides shooters, dead-time generation, short-circuit and thermal protection against overload.

Part of the IC’s functionality, is that it can generate regulated voltage levels for powering low-side switches. It features a sense input to add voltage remotely for improved performance and a VDD which accepts up to +20V and enables the IC to work with a wide supply range. It also features enable pins to turn the levels ON/OFF.

The device offers three types of fault reporting: over-temperature, yellow fault (Yf), and protective fault (Pf). It offers excellent transient and thermal performances, providing higher efficiency and reliability for automotive applications. The device operates between -40 °C and +150 °C and offers the complete protection of the overload, under-voltage, short-circuit, etc., in automated process.

The integrated circuit has a wide application field, ranging from supplying high-current switches in multiple power modules, to driving solenoid valves, actuators, and relays. It also finds application in systems with DC-DC conversion, auxiliary power supplies, LED lighting systems, and battery management.

IR2132SPBF can be find in two different versions: the IR2132S and the IR2132SP. The only difference is that the IR2132SP allows for a remotely connected GND, for improved thermal performance, at the expense of a slightly higher cost. Both are current-limited gate drivers with a galavanic isolation. They use IC technology to drive high and low side switches with 600V and 200mA.

The working principle of the IR2132SPBF is based on a feedback loop. It is one of the only gate drivers that features its own current limitation, allowing it to control the currents of the switch. It uses a control logic to turn the switch ON or OFF, while the feedback loop will provide a signal to the control logic based on the output current, activating the switch if the current is lower than the predetermined limit.

In conclusion, it can be said that the IR2132SPBF integrated circuit is an innovative IC designed for automotive applications. It serves as an excellent gate driver, providing an efficient, reliable and safe switching operation. Its current limiting feature and fault protection capabilities ensure safe operation of switches, while its wide application field allows it to be used in a wide range of power management systems.
