What are the key features of LTC4440IMS8E#TRPBF?
- 2.4 A peak source and sink gate drive current enables fast switching of large N-channel MOSFETs in high-side configurations
- Bootstrap gate drive architecture supports N-channel high-side FETs with gate voltages up to 5.5 V above the supply rail
- Schmitt trigger input with hysteresis provides noise-immune logic level translation for PWM signals in noisy power converter environments
- MSOP-8 with exposed pad reduces package thermal resistance and board footprint compared to standard MSOP or SOIC packages
What is LTC4440IMS8E#TRPBF used for?
LTC4440IMS8E#TRPBF is used as a high-side gate driver in synchronous buck converters, H-bridge motor drives, and LED dimming circuits where N-channel MOSFETs are preferred for low on-resistance. The 2.4 A peak drive current allows switching frequencies above 1 MHz with large-gate FETs, supporting compact switching power supply designs. Automotive and industrial power systems benefit from its Schmitt trigger input immunity and wide supply range.

Frequently Asked Questions
What peak gate drive current does LTC4440IMS8E#TRPBF deliver and why does it matter for high-frequency switching?
LTC4440IMS8E#TRPBF delivers 2.4 A peak gate drive current, which rapidly charges and discharges MOSFET gate capacitance. Faster switching transitions reduce cross-conduction losses in synchronous buck converters operating at 500 kHz to 2 MHz, improving efficiency in point-of-load power supplies used in server and telecom equipment.
How does the bootstrap architecture in LTC4440IMS8E#TRPBF enable driving N-channel high-side MOSFETs?
The bootstrap circuit in LTC4440IMS8E#TRPBF charges a small external capacitor to the supply voltage during the low-side phase, then uses this stored charge to bias the gate 5.5 V above the source of the high-side N-channel FET. This eliminates the need for a separate isolated gate supply, simplifying designs in 12 V to 48 V DC-DC converter stages.
Is LTC4440IMS8E#TRPBF suitable for H-bridge full motor control applications, and what supply range is supported?
Yes, LTC4440IMS8E#TRPBF can drive high-side switches in full H-bridge and half-bridge motor control circuits. The device supports an input bootstrap voltage range compatible with 4.5 V to 13.5 V motor supply rails, and its 2.4 A drive capability handles MOSFETs with gate charge up to 100 nC at switching frequencies of several hundred kilohertz.
