Frequently Asked Questions
What are the key electrical specifications of the LM5111-2MY?
The LM5111-2MY operates from a 4.5V to 18V supply voltage and delivers 5A peak sink current and 1A peak source current per channel. It features 5ns typical rise and fall times and independent inputs for each of the two driver channels, making it suitable for high-frequency switching applications.
What applications is the LM5111-2MY designed for?
The LM5111-2MY is designed for MOSFET gate driving in synchronous DC-DC converters, half-bridge and full-bridge topologies, class-D audio amplifiers, motor drivers, and resonant power supplies. Its high peak current output and fast switching times make it particularly effective in high-frequency power conversion circuits.
What package does the LM5111-2MY come in and what are its dimensions?
The LM5111-2MY is available in a SOT-23-6 (6-pin small outline transistor) surface-mount package. This compact package is approximately 2.9mm × 1.6mm, which is ideal for space-constrained PCB designs in portable and industrial applications.
Can the LM5111-2MY be used as a half-bridge gate driver?
Yes, the LM5111-2MY can be configured as a half-bridge gate driver. Its two independent input channels allow individual control of the high-side and low-side MOSFETs. However, it is a low-side driver without built-in bootstrap circuitry, so external level-shifting or a dedicated high-side supply is required for floating high-side gate drive.
What is the price and availability of the LM5111-2MY?
The LM5111-2MY is priced from approximately $0.84 per unit. It is a standard Texas Instruments product available through major distributors worldwide, with in-stock inventory supporting both prototype quantities and production volume orders with fast shipping options.
