The LTC7001HMSE is a dual channel device which features adjustable deadtime, independent shutdown, and fault detection. It is suitable for high switching frequencies, up to >200kHz.

Application Area and Working Principle

The LTC7001HMSE#PBF belongs to the PMIC (Power Management Integrated Circuit) – Gate Drivers family and is suitable for a wide range of applications. It can be used in industrial and power control applications such as AC-DC and DC-DC high-current power supplies, uninterruptible power supplies, and motor drivers. This device is also suitable for power converters using high-voltage MOSFETs and IGBTs.

The LTC7001HMSE#PBF is a dual-channel isolated gate driver designed with high performance, low output leakage, and increased safety. This gate driver can operate up to 25V breakdown voltage and features adjustable deadtime for precise control of the gate switch timing. The device also features independent shutdown control, enabling each of the two channels to be enabled/disabled independently for optimized power consumption.

The LTC7001HMSE also features a fault detection circuit which monitors the gate switch voltage, ensuring the device switches properly. This circuit will quickly detect any undervoltage or overvoltage in the gate switch and will activate a fault output pin if the voltage rises above or below the specified threshold. Furthermore, the device is designed to remain in a low-power mode when disabled, allowing it to be easily integrated into power-sensitive applications.

The LTC7001HMSE#PBF is constructed on a monolithic substrate and features on-chip bootstrap diodes for gate drive supplies up to 25V. This guarantees the device operates reliably and efficiently over the long term. The device is also designed to reduce EMI (Electro Magnetic Interference) and RFI (Radio Frequency Interference) through the use of dedicated internal EMI filters.

Conclusion

The LTC7001HMSE#PBF is a high-performance isolated gate driver that belongs to the PMIC – Gate Drivers family of components. This device is suitable for power control applications such as AC-DC and DC-DC power supplies, uninterruptible power supplies, and motor drivers. The LTC7001HMSE#PBF features adjustable deadtime, independent shutdown, and fault detection to ensure reliable operation. Furthermore, its low-power modes reduce power consumption and its on-chip bootstrap diodes guarantee a reliable operation over time.
