Overview

Description

The LTC4446EMS8E#PBF is a dual MOSFET gate-driver IC from Linear Technology (now Analog Devices). It provides two independent gate drivers to drive a pair of N‑channel MOSFETs in a half‑bridge or two separate channels, suitable for switching regulators, buck/boost converters, and motor drives. The high‑side driver uses a bootstrap supply, enabling gate drive above the input supply, while the low‑side driver references ground. It includes protections such as undervoltage lockout, shoot‑through prevention, and dead‑time control, and accepts CMOS/TTL‑level logic inputs to rapidly source/sink gate currents. The EMS8E suffix denotes an 8‑pin RoHS‑compliant package (MSOP/DFN style), and #PBF indicates Pb‑free packaging. Typical pins: Vcc, Gnd, IN1/IN2, HO/LO outputs, and VB/VS for the high‑side bootstrap.

Features

LTC4446EMS8E#PBF features (concise):
- Dual high-side/low-side MOSFET gate drivers for synchronous buck/boost topologies
- Bootstrapped high-side supply for N-channel MOSFETs
- Independent input/output channels with push-pull drive
- Enable input for each channel
- Undervoltage lockout on both drivers
- Shoot-through protection with dead-time control
- Overcurrent/short-circuit protection
- Suitable for high-speed, high-efficiency switching applications
- 8-lead EMS8E Pb-free package
Note: For exact electrical specs (drive strength, voltage range, timing, etc.), refer to the official datasheet.

Package

An 8-pin MSOP (Plastic Small-Outline) package, RoHS lead-free (PBF).

Pinout

Pin count: 8 pins (EMS8E indicates an 8-pin package).
Function: LTC4446EMS8E#PBF is a dual MOSFET gate-driver IC (two outputs) used to drive a high-side and a low-side N-channel MOSFET in a half-bridge topology. It provides gate drive with features such as level shifting/bootstrapping, undervoltage lockout, and enable/dead-time control typical of high-voltage switching regulators.
