Texas Instruments Dual Half Bridge Gate Driver VSSOP-10

The Texas Instruments Dual Half Bridge Gate Driver is a 100V half-bridge gate driver in a compact VSSOP-10 package, designed to drive high-side and low-side N-channel MOSFETs with precise control and high efficiency in power conversion circuits.

Overview

The floating high-side driver can operate with rail voltages of up to 100V, making it suitable for medium to high-voltage applications. It is ideally suited to synchronous buck converters and half-bridge topologies. The driver incorporates a single TTL-compatible control input along with an enable pin, allowing straightforward integration into digital control systems.

Key Features

• Programmable dead-time set by a single external resistor, helping to optimise switching transitions and minimise shoot-through current
• Single TTL-compatible control input with enable pin
• Floating high-side driver with rail voltage of up to 100V
• Under-voltage lockout (UVLO) that disables the gate driver outputs if the low-side or bootstrapped high-side supply voltage falls below the operational threshold
• Typical turn-off propagation delay of 32 ns, with configurable turn-on delays
• Source current of 1.2 A and sink current of 1.8 A
• Advanced, robust level-shift technology enabling high-speed operation with low power consumption
