The 1SP0335V2M1-45 is an integrated gate driver ideal for high side and low side devices. It features very low on-resistance and is designed for use in DC to DC converters in switching power supplies. This device is most suitable for applications that require a wide supply voltage range or a high turn-on voltage. The 1SP0335V2M1-45 supports a range of input supply voltages from 18V to 65V and has an adjustable output voltage. It can be used to drive devices such as MOSFETs, IGBTs, integrated gate drivers, and reverse bias PIN diodes. In addition, the 1SP0335V2M1-45 has an internal overtemperature shutdown feature that protects the device against thermal damage. The device also has a built-in thermal sensor that monitors power dissipation and provides a warning of an over-temperature event.

Application Field

The 1SP0335V2M1-45 is most suitable for use in offline power converter designs in applications such as isolated voltage regulators, isolated switch mode power supplies, isolated DC/DC converter control circuits, and other isolated circuitry. The device also has good performance in applications that need low on-resistance and high turn-on voltage, such as LED drivers, switched-capacitor converters, hot swap controllers, and motor drives. Additionally, the 1SP0335V2M1-45 is suitable for use in high temperature environments due to its thermal shutdown feature.

Working Principle

The 1SP0335V2M1-45 uses an internal MOSFET to drive and control the output pin. Its Gate Driver output is an open-drain output, so the output voltage can be adjusted by the pull-up voltage connected to the output pin. The Gate Driver output can be driven over a wide supply voltage range and is rated to drive up to 500 mA. The output current can be adjusted by the external resistor connected to the output pin. The 1SP0335V2M1-45 also has an internal peak current detect feature which limits the peak output current and protects the IC from over current conditions.

The 1SP0335V2M1-45 includes a built-in overtemperature shutdown circuit that automatically trips when the junction temperature of the device exceeds a certain level. This provides protection from thermal damage. The temperature shutdown is triggered at a pre-set level, which can be adjusted by selecting the appropriate external temperature sensing resistor.

The 1SP0335V2M1-45 is designed for high performance and reliability in a wide range of applications. The device has been tested to meet the requirements of Safety and Reliability Standards, including Underwriters Laboratories and International Electro-Technical Commission (IEC) standards.

Conclusion

The 1SP0335V2M1-45 integrated gate driver is an ideal solution for high and low side switching applications which require high performance and reliability. It features very low on-resistance and an adjustable output voltage. The device also has an overtemperature shutdown feature for added protection. The 1SP0335V2M1-45 is most suitable for use in DC to DC converters in switching power supplies, LED drivers, switched-capacitor converters, hot swap controllers, and motor drives.
