LM5108DRCT High-Voltage Half-Bridge Gate Driver
The LM5108DRCT is a high-voltage, high-performance half-bridge gate driver from Texas Instruments, designed to efficiently control N-channel MOSFETs and IGBTs in power conversion applications. This driver operates with bootstrap supply voltages up to 100V, making it ideal for motor drives, switch-mode power supplies (SMPS), and DC-DC converters. Its wide input voltage range (8V to 14V) ensures compatibility with various control circuits while providing robust performance in high-power systems.
Engineered for fast switching and minimal power loss, the LM5108DRCT features 1.5A peak source and 2.5A peak sink current capability, enabling rapid turn-on and turn-off of power switches. The device incorporates adaptive dead-time control, preventing shoot-through currents in half-bridge configurations and improving system reliability. Its UVLO (Undervoltage Lockout) protection on both VDD and VHB supplies ensures safe operation by disabling outputs when voltages fall below threshold levels. Packaged in a compact 10-pin VSON (DRC) package, this driver is optimized for high-density power electronics designs.
