- 1.1 A peak output current capability for fast MOSFET switching in high-side half-bridge and full-bridge power stages
- Gated Schmitt trigger input improves noise immunity and prevents false triggering in electrically noisy power conversion environments
- 8-pin MSOP with exposed pad (MSOP-EP) offers a compact 3x3 mm footprint with enhanced thermal dissipation
- High-side driver architecture with bootstrap supply support enables direct N-channel MOSFET drive above supply rail voltage
What is LTC4440EMS8E-5 used for?
The LTC4440EMS8E-5 is used to drive high-side N-channel MOSFETs in synchronous buck converters, half-bridge and full-bridge motor driver stages, and class-D audio amplifiers operating from supplies up to the device's rated bootstrap voltage. Its 1.1 A drive capability enables rapid charge and discharge of large gate capacitances, reducing switching losses at frequencies above 100 kHz. The compact MSOP-EP package makes it well-suited for space-constrained DC-DC converter modules and power management ICs in industrial and consumer electronics.

Frequently Asked Questions
What peak output current does the LTC4440EMS8E-5 deliver, and what topologies does it support?
The LTC4440EMS8E-5 provides 1.1 A peak output current and supports high-side drive in both half-bridge and full-bridge converter topologies. Its non-inverting output polarity ensures the driven MOSFET turns on and off in direct response to the input signal without additional inversion logic.
How does the gated Schmitt trigger input on the LTC4440EMS8E-5 benefit noisy power converter designs?
The gated Schmitt trigger input adds hysteresis to the switching threshold, typically around 0.5 V, which prevents spurious gate pulses caused by PCB noise or coupled transients. This is especially valuable in high-frequency switching regulators above 200 kHz where rapid dV/dt transitions can couple into logic-level control signals.
Which package does the LTC4440EMS8E-5 use and how does the exposed pad improve thermal performance?
The LTC4440EMS8E-5 is housed in an 8-pin MSOP with exposed pad (MSOP-EP). The exposed pad provides a low thermal resistance path to the PCB ground plane, reducing junction-to-board thermal resistance compared to a standard MSOP-8 package, which is beneficial when driving high capacitance MOSFET gates at switching frequencies above 500 kHz.
When would a designer choose the LTC4440EMS8E-5 over a lower current gate driver in a synchronous buck converter?
A designer would select the LTC4440EMS8E-5 when the high-side MOSFET has a gate charge above 20 nC and switching frequency exceeds 200 kHz, where a 1.1 A driver significantly reduces turn-on and turn-off transition times, lowering switching losses and improving converter efficiency compared to 400 mA or 600 mA alternatives.
