What are the key features of LT1161IN#PBF?
- Quad-channel (4 independent drivers) high-side N-channel MOSFET gate driver reduces component count in multi-switch power control designs
- High-voltage capability supports high-side switching above the supply rail using bootstrap or charge-pump techniques for N-channel MOSFET control
- Gated Schmitt trigger inputs provide noise immunity and hysteresis, preventing false triggering from slow-rise or noisy control signals
- Totem-pole output stage delivers fast gate charging and discharging for low switching losses in power MOSFET applications
- 20-pin DIP (R-PDIP-T20) package enables breadboard prototyping and through-hole production assembly for industrial power designs
What is LT1161IN#PBF used for?
The LT1161IN#PBF is used in multi-channel high-side switching circuits, H-bridge motor drives, and DC-DC converter topologies where 4 independent N-channel MOSFET gates must be driven from a single IC. Its gated Schmitt trigger inputs and totem-pole outputs make it well-suited for industrial power management modules, solenoid drivers, and high-side load switches in programmable logic controller (PLC) output stages.

Frequently Asked Questions
How many MOSFET channels can the LT1161IN#PBF drive simultaneously, and what type of MOSFETs does it target?
The LT1161IN#PBF drives 4 independent channels, each targeting an N-channel MOSFET configured in a high-side switching topology. With 4 totem-pole outputs, a single LT1161IN#PBF can control 4 separate high-side N-channel MOSFETs in one DIP-20 package, reducing component count in multi-channel motor drives, solenoid controllers, or multi-phase DC-DC converters.
What does the Schmitt trigger input in the LT1161IN#PBF provide in noisy industrial environments?
The gated Schmitt trigger input of the LT1161IN#PBF provides hysteresis, typically several hundred millivolts, that prevents the gate driver output from toggling in response to slow or noisy logic transitions. In industrial environments with electrical noise from motor drives, relays, or switching supplies, this hysteresis ensures the 4-channel MOSFET driver only switches when the input signal crosses both the upper and lower threshold levels, improving system noise immunity.
What package does the LT1161IN#PBF use, and how does this affect prototyping and production assembly options?
The LT1161IN#PBF is housed in a 20-pin DIP (PDIP-T20) through-hole package, which is compatible with standard 0.100" (2.54 mm) pitch breadboards and IC sockets for rapid prototyping. In production, the through-hole DIP-20 format supports wave soldering and hand soldering without specialized SMT reflow equipment, making it practical for low-to-medium volume industrial power control boards.
In which power topologies is the LT1161IN#PBF most commonly used as a high-side gate driver?
The LT1161IN#PBF is most commonly used in H-bridge motor drives requiring 2 or 4 high-side N-channel MOSFETs, synchronous buck DC-DC converters needing high-side switch control, and multi-channel solenoid drivers in PLC output modules. Its 4-channel architecture supports full-bridge and multi-phase topologies where individual control of each high-side MOSFET gate at switching frequencies typical of power electronics is required.
