PMIC - Gate Drivers are key components for automotive and industrial control, providing a reliable and efficient interface between the control signal and power elements. The LT1336IS#TRPBF is a highly efficient gate driver, capable of providing switching at low and medium frequencies, and also having protection against inrush current, voltage and temperature spikes. In this article we will look at its application field and working principle.

Application Field

The LT1336IS#TRPBF is a single-channel, low-current, low-power-consumption gate driver, designed for use in automotive and industrial systems. It is particularly suited for use in standard low-frequency (LF) and medium-frequency (MF) control circuits. It is compatible with most logic levels, including both LVTTL and CMOS, as well will operate with input voltages up to 36 volts.

It is designed to drive N-Channel MOSFETs, IGBTs, TRIACs and SCRs, making it a suitable choice for most standard control applications. The device has a maximum operating temperature rating of +135°C and is both RoHS compliant and AEC-Q100 qualified, making it suitable for both commercial and industrial applications.

The LT1336IS#TRPBF can be used in a variety of applications, including but not limited to cooling, heating, lighting and motor control, as well as for switching digital logic systems. Additionally, the device has built-in protections for inrush current, voltage surges and temperature spikes, making it a suitable choice for systems requiring a higher level of robustness.

Working Principle

The LT1336IS#TRPBF is composed of three primary components: a shift register, a drive circuit, and a voltage regulator. The shift register is responsible for receiving and storing the logic control signals. The logic signals are then used to drive the MOSFETs, IGBTs, TRIACs and SCRs via the drive circuit. Finally, the voltage regulator ensures that the power supplied to the device is at the correct voltage and is optimized for the device\'s current level.

The device works by receiving a logic control signal, which is passed through the shift register. This signal is then used to control either the p- or n-channel MOSFETs, IGBTs, TRIACs or SCRs. Depending on the type of logic control signal, the appropriate device is turned on or off providing an efficient switch for the circuit. The voltage regulator provides the voltage stabilization needed for the device to operate efficiently and protect the circuit from both inrush current and voltage surges. Finally, the device is protected from temperature spikes and thermal runaway due to the use of the optimized voltage regulator.

Conclusion

The LT1336IS#TRPBF Gate Driver is a highly efficient and robust solution for use in automotive and industrial control circuits. It is designed to efficiently switch low and medium frequency signals, as well as have protections against inrush current, voltage and temperature spikes. It is suitable for use in a variety of applications, including cooling, heating, lighting, motor control, and switching digital logic systems. The device is both RoHS compliant and AEC-Q100 qualified, making it a suitable choice for both commercial and industrial applications.
