- 10-year YTEOL product availability horizon supporting long-lifecycle motor control and power conversion equipment
What is LT1160IS#PBF used for?
The LT1160IS#PBF is designed for half-bridge and full-bridge power converter stages used in brushed DC motor drives, synchronous buck regulators, and H-bridge inverter circuits. Its high-side and low-side gate drive outputs enable direct control of N-channel MOSFETs in both switch positions without the need for isolated bootstrap driver ICs in many applications. The device is also well suited for UPS systems, solar inverters, and industrial servo drives where reliable MOSFET switching under high-current, high-noise conditions is essential.

Frequently Asked Questions
Can LT1160IS#PBF drive both high-side and low-side MOSFETs in a half-bridge stage?
Yes. The LT1160IS#PBF is specifically designed as a half-bridge MOSFET driver, providing both high-side and low-side gate drive outputs from a single 14-pin SOIC IC. This eliminates the need for two separate gate driver ICs in a half-bridge topology, reducing BOM cost and simplifying PCB layout for motor drives and synchronous converters.
How do the Schmitt-trigger inputs on LT1160IS#PBF improve reliability in noisy power circuits?
Schmitt-trigger inputs introduce hysteresis — typically tens of millivolts — between the rising and falling switching thresholds, preventing false triggering caused by conducted or radiated noise on control signal lines in switching power supplies operating at high voltages and currents. This is critical in motor drive applications where PWM lines run near high-di/dt switching nodes.
What output stage topology does LT1160IS#PBF use and why does it matter for gate drive speed?
The device uses totem-pole (push-pull) outputs, which source and sink gate drive current actively in both directions. Unlike open-drain outputs that rely on a pull-up resistor for the off transition, totem-pole drivers achieve faster MOSFET turn-off — critical for reducing switching losses in converters operating above 50 kHz.
In a synchronous buck converter design, what advantage does the single-IC half-bridge approach of LT1160IS#PBF offer over discrete solutions?
Integrating both high-side and low-side gate drivers into one 14-pin SOIC package reduces PCB routing between two separate ICs, lowers propagation delay mismatch between the two gate drive signals, and shrinks the total gate drive footprint by roughly 50% compared to two SOT-23 or SO-8 discrete drivers, while the Schmitt inputs add built-in noise margin without external RC filtering.
