Description

UCC27516DRSR is a Texas Instruments MOSFET gate driver in the UCC27516 family. It provides fast, high‑current gate drive for external N‑channel MOSFETs used in switching power converters. The device translates a logic input into a drive signal capable of quickly charging and discharging the MOSFET gate, enabling high‑frequency operation with low switching losses. Typical features include undervoltage lockout, an enable input, protection against mis-operation, and controlled output rise/fall times. The DRSR suffix indicates a specific packaging variant; check the datasheet for exact pinout and electrical specs. Common applications are buck/boost/DC‑DC converters, synchronous rectification, point‑of‑load regulators, and motor‑drive front ends. For precise specifications (drive current capability, voltage range, propagation delay, protections), consult the UCC27516DRSR datasheet and TI design resources.

Features

UCC27516DRSR is a high-speed, single-channel MOSFET gate driver. Key features include:
- Up to 16 A peak source/sink gate-drive current for fast switching
- Wide operating supply: 4.5 V to 18 V
- Logic inputs compatible with 3.3 V/5 V controllers
- Push-pull output to drive N-channel MOSFET gates
- Undervoltage lockout (UVLO) with hysteresis
- Enable input to force output off
- Very fast propagation and edge rates (typical nanosecond-scale)
- RoHS-compliant 8-pin DSR package (DRSR suffix)
Applications include DC-DC, motor drives, and other switching power-conversion circuits. For exact electrical specs ( voltages, delays, margins, and pinout), consult the TI UCC27516 datasheet.

Package

8-pin SOIC package (D package) for UCC27516DRSR.

Pinout

- Pin count: 8 pins (8‑pin package, DSR suffix indicates a small-outline package).
- Function: UCC27516DRSR is a dual high‑speed MOSFET/IGBT gate driver for half‑bridge applications. It provides two outputs: HO (high‑side) and LO (low‑side), driven by logic inputs (IN and EN). It is powered from VCC with a GND reference and uses a bootstrap supply (VB/VS) for the high‑side drive, delivering fast source/sink gate currents to switch the transistors.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, embedded processing, and other semiconductor products.

Application

UCC27516DRSR is a high-speed MOSFET gate driver. Typical applications include:
- Driving MOSFETs in switching power supplies (buck/boost/flyback) and isolated/non-isolated SMPS
- Synchronous rectification in DC-DC converters
- High-speed PWM gate driving for motor control (BLDC/stepper) and other fast-switching power electronics

Equivalent

There isn’t an exact cross-reference for UCC27516DRSR. Closest functionally are TI’s other UCC275xx devices (e.g., UCC27512, UCC27515, UCC27517). External options include common MOSFET gate drivers like Infineon’s IR2110/IR2113. For a precise substitution, share your required specs (Vcc, drive current, bootstrap/isolated, package) and I’ll map a cross-reference.
