UCC27200DDAR

The UCC27200DDAR is TI’s dual MOSFET gate-driver IC designed to drive a half-bridge (one high-side and one low-side N‑channel MOSFET). It provides separate HO (high-side) and LO (low-side) outputs and uses a bootstrap circuit (VB–VS) to drive the high-side gate above the supply.
Key points:
- Independent inputs for each leg and fast gate-drive capability to minimize switching losses.
- Bootstrap high-side drive with VB, VS pins; requires a bootstrap capacitor and proper decoupling.
- Protection features such as undervoltage lockout and fault protection, plus dead-time/shoot-through mitigation.
- Logic inputs typically compatible with 3.3 V/5 V control signals.
- Package: 8-pin DDAR (TI’s RoHS tape-and-reel option for an 8-pin package).
Applications:
- Half-bridge in switch-mode power supplies, DC-DC converters, motor drives, and inverter stages.
Notes:
- Ensure correct bootstrap charging, layout, and decoupling for reliable operation.

Key features of UCC27200DDAR (gate driver):
- Dual high-side and low-side gate driver (independent inputs) for N-channel MOSFETs
- 2 A peak source/sink drive per channel
- Bootstrapped high-side drive (VB–VS) with drive voltage ≈ VDD
- Logic supply range: VDD 4.5 V to 18 V; TTL/CMOS-compatible inputs
- UVLO protection on VDD (and VB) with hysteresis to prevent false triggering
- Enable/shutdown control and input buffering
- Internal dead-time/shoot-through protection to prevent cross-conduction
- Outputs: HO (high-side) and LO (low-side) suitable for fast switching
- Wide temperature range: -40°C to 125°C
- 8-pin package in DDAR variant (ROHS-compliant; check packaging spec)
Note: For exact electrical characteristics (propagation delay, rise/fall times, UVLO thresholds, etc.), refer to the datasheet.

8 pins. Function: UCC27200DDAR is a dual, non-inverting, high-speed MOSFET gate driver. It provides two gate-drive outputs (one per channel) controlled by two input signals, with Vcc and GND pins and an enable/shutdown input. Used to drive two N-channel MOSFETs in switch-mode power supplies or half-bridge configurations.
