LTC4440ES6-5#TRPBF

Overview

The LTC4440ES6-5#TRPBF is a high-speed, high-voltage N-channel MOSFET gate driver manufactured by Analog Devices Inc. It operates in a single-channel, non-inverting configuration within a TSOT-23-6 surface-mount package. The device supports a bootstrap supply voltage up to 80V and accepts logic inputs with thresholds of 1.3V (VIL) and 1.6V (VIH). It delivers peak output currents of 2.4A for both sourcing and sinking. Typical switching characteristics include rise and fall times of 10ns and 7ns respectively. The component functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• High-side driving capability for N-channel MOSFETs with integrated bootstrap support
• Non-inverting input logic compatible with low-voltage control signals
• High peak output current drive for rapid MOSFET switching transitions

Applications

• High-side switching in synchronous buck converters
• Half-bridge and full-bridge power stage drivers
• Motor control applications requiring high-side N-channel FET actuation

Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging when ordering. Confirm the -5 variant matches required logic voltage thresholds. Ensure the TSOT-23-6 footprint aligns with PCB layout constraints. Validate RoHS compliance status against current regulatory requirements. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid counterfeit components.

Selection Notes

Select this component when driving high-side N-channel MOSFETs in compact designs. The TSOT-23-6 package suits space-constrained applications. Verify that the 80V maximum supply rating exceeds the circuit's peak voltage. Ensure the 2.4A peak current meets the gate charge requirements of the target MOSFET. Check compatibility with the system's logic voltage levels before integration.

Part Context

This part belongs to the LTC4440 family of high-voltage gate drivers designed for efficient power management. It complements controllers like the LTC3780 in reference designs such as DC1046A. The device enables simplified high-side drive solutions without external level shifters or complex bootstrap circuits beyond standard capacitor requirements.
