Product Introduction

Overview

The FAN3180TSX, produced by onsemi, is a single 2-A low-side gate driver integrated with a 3.3-V Low Drop Out (LDO) regulator. This component is designed to drive N-channel enhancement-mode MOSFETs in low-side switching applications. It combines high-speed gate driving capabilities with a stable 3.3-V output voltage regulator, making it suitable for powering external microcontrollers or ASICs. The device features a MillerDrive™ architecture, which enhances switching performance by providing high peak currents during the MOSFET turn-on and turn-off process.

Key Features

  • High-Speed Gate Driver: Capable of delivering peak currents of 2.8 A (sinking) and -2.5 A (sourcing) at VDD = 12 V.
  • Integrated 3.3-V LDO Regulator: Provides a stable 3.3-V output with ±1% voltage tolerance at 25°C and ±2.5% total variation, capable of sourcing up to 15 mA.
  • MillerDrive™ Architecture: Enhances switching performance by providing high peak currents during the MOSFET turn-on and turn-off process.
  • TTL-Compatible Input Thresholds: Input thresholds meet industry-standard TTL logic levels, independent of VDD voltage.
  • Under-Voltage Lockout (UVLO): Ensures the output remains low until the supply voltage is within the operating range and the first full input pulse is detected.
  • Thermal Shutdown: Provides an additional safety feature to prevent overheating.
  • Low Standby Current: Maximum standby supply current of 200 µA.
  • Wide Operating Temperature Range: Operates from -40°C to +125°C.

Applications

  • Gate Drive with Power for MCU: Ideal for applications requiring both a gate driver and a power source for microcontrollers or ASICs.
  • Switched-Mode Power Supplies: Suitable for high-frequency power converter designs.
  • Consumer Electronics: Used in various consumer electronic devices requiring efficient power management.
  • Portable Hand Tools: Applicable in portable hand tools that require reliable and efficient power management.
