LM5104M General Description

The LM5104M is a versatile high-voltage gate driver that offers advanced features for driving both high-side and low-side N-channel MOSFETs in a synchronous buck configuration. With a floating high-side driver capable of operating with supply voltages up to 100V, this driver provides the flexibility needed for various power management applications. The adaptive manner in which the high-side and low-side gate drivers are controlled helps prevent shoot-through issues, ensuring smooth and efficient operation. Additionally, the device allows for customizable transition timing with the option to add extra delay time using an external setting resistor

Key Features

Precision output voltage regulation with high accuracy
Fault-tolerant architecture with automatic recovery
Soft-start and shutdown capabilities for safety
Digital current limit detection and regulation
Overcurrent protection and short-circuit protection
Safe operation even under transient conditions
