UCC27512DRSR

UCC27512DRSR is TI’s single-channel, high-speed MOSFET gate driver in an 8-pin DSR package. It provides a push-pull output to rapidly drive an external N-channel MOSFET gate, reducing switching losses and easing the workload on the controller. It accepts a TTL/CMOS input and translates it into a gate-swing at OUT referenced to COM. Features typically include undervoltage lockout and robust drive capability. Applications: DC–DC converters, synchronous rectifiers, motor drivers, and other switching power-supply topologies. Typical pinout: VCC, GND (COM), IN, OUT (plus NCs/extra pins). The DRSR suffix denotes packaging and RoHS-compliance. For use: provide VCC, connect COM to the MOSFET source, decouple VCC, drive IN with a logic-level signal, and add a small series gate resistor as needed to control ringing.

Key features of UCC27512DRSR (TI):
- Dual high-speed MOSFET gate drivers with independent outputs.
- Fast source/sink capability to quickly charge/discharge gates.
- Wide drive-supply range: VCC typically 4.5 V to 20 V.
- Logic inputs compatible with TTL/CMOS (3.3/5 V logic levels).
- Undervoltage lockout on VCC to prevent false switching.
- Protection features: short-circuit/overcurrent protection and thermal shutdown.
- Shoot-through prevention and low output skew with fast propagation delays (suitable for high-speed switching).
- Enable/disable control and simple, robust operation in half-bridge or dual high-side/low-side applications.
- Packaging: 8-pin DRSR (high-volume reel packaging) suitable for surface-mount designs.
Applications include gate driving for synchronous buck/boost converters, motor drives, and other MOSFET driver needs where fast, dual-channel, non-isolated gate drive is required.

- Pin count: 8 pins (SOIC-8, DRSR package).
- Function: High-speed MOSFET gate driver with bootstrap high-side capability. Provides HO (high-side) and LO (low-side) outputs to drive a half-bridge; inputs IN and INB control the outputs; VCC and GND supply the device; VB and VS are bootstrap pins for the high-side driver (with UVLO/overcurrent protections).

- Manufacturer: Texas Instruments (TI)
- What kind of company: American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing ICs (headquartered in Dallas, Texas).

Applications:
- High-speed gate driver for N-channel MOSFETs/IGBTs in switching power supplies (SMPS)
