LTC4440ES6-5#TRMPBF

Overview

The LTC4440ES6-5#TRMPBF is a high-side gate driver IC manufactured by Analog Devices Inc., designed for driving N-channel MOSFETs. It features a single channel with non-inverting input logic and operates within a supply voltage range of 4V to 15V. The device supports peak output currents of 2.4A for both sourcing and sinking. It accommodates bootstrap voltages up to 80V and includes logic thresholds compatible with 1.3V (VIL) and 1.6V (VIH). Typical switching characteristics include rise and fall times of 10ns and 7ns, respectively. The component is housed in a TSOT-23-6 package and functions reliably across an operating temperature range of -40°C to 85°C.

• Industrial motor drive gate driving systems

Procurement Notes

Verify the specific suffix TRMPBF against official Analog Devices documentation to confirm tape-and-reel packaging specifications and RoHS compliance status. Ensure that the ordering information matches the exact part number variant required for your design, as suffixes may indicate differences in packaging or environmental certifications without altering the core electrical function. Cross-reference datasheet revision dates to guarantee parameter accuracy.

Selection Notes

Select this component when a compact high-side driver is required for N-channel MOSFETs in automotive or industrial environments. The 80V bootstrap rating suits applications with higher bus voltages, while the TSOT-23-6 package aids in miniaturization. Confirm that the 2.4A peak current capability aligns with the target MOSFET gate charge requirements and that the 4V-15V supply range matches the available control logic voltage levels.

Part Context

This part belongs to the LTC4440 family of high-speed, high-voltage gate drivers from Analog Devices. It is frequently paired with controllers like the LTC3780 in reference designs such as the DC1046A buck-boost converter. The ES6-5 designation indicates the specific package type and logic threshold variant within the broader product line, ensuring compatibility with standard low-voltage digital interfaces.
