TC4427ACOA713 – 1.5A Dual High-Speed Power Mosfet Driver IC SOP-8

TC4427ACOA713 – 1.5A Dual High-Speed Power Mosfet Driver IC SOP-8 delivers high-peak current drive capability with minimal propagation delay to optimize high-frequency switching applications. This dual non-inverting MOSFET driver efficiently translates low-level logic signals into robust voltage levels required for rapid gate charge injection. Consequently, power stage switching losses decrease substantially across switch-mode power supplies and motor controllers. Furthermore, the IC features matched rise and fall times to eliminate shoot-through risks in complementary driver topologies. Therefore, embedded systems engineers can seamlessly pair digital microcontrollers with high-current MOSFETs or IGBTs without compromising switching speed or stability.

Key Features:

• High Peak Output Current: Delivers up to 1.5A peak current to quickly charge power transistor gate capacitance, minimizing turn-on and turn-off transition times.
• Wide Supply Voltage Range: Operates efficiently across a broad supply voltage window of 4.5V to 18V for flexible power rail integration.
• Matched Speed and Delay: Features matched rise and fall times under 25 ns alongside short propagation delays of ≈ 40 ns for precise high-frequency control.
• CMOS/TTL Compatible Inputs: Accepts logic control inputs up to the supply voltage level without requiring external level-shifting circuitry.
• Latch-Up Resistant: Withstands over 500 mA of reverse current on outputs without damage or latch-up risks in noisy industrial environments.
