Description

The IR2104 is specifically designed to drive both the high-side and low-side transistors in a half-bridge circuit. It features independent high-side and low-side outputs, which are used to control the switching of the transistors. The high-side driver is powered via a bootstrap capacitor, allowing the IC to drive the high-side N-channel MOSFET/IGBT up to 600V. This makes the IR2104 ideal for use in motor drives, inverters, and other high-voltage applications.

Features

  • Half-Bridge Driver: Designed to drive both high-side and low-side N-channel MOSFETs or IGBTs in a half-bridge configuration.
  • Bootstrap Circuitry: Integrated bootstrap diode enables high-side operation with a bootstrap capacitor, simplifying the circuit design.
  • High-Speed Operation: Capable of driving transistors at high switching frequencies, with typical propagation delays of around 120 ns.
  • Undervoltage Lockout (UVLO): Provides protection for both the high-side and low-side drivers by shutting down the outputs if the supply voltage drops below a certain threshold.
  • Shoot-Through Protection: Built-in dead-time control to prevent both the high-side and low-side transistors from being on simultaneously, thus avoiding shoot-through currents.
  • CMOS/TTL Compatible Inputs: Logic inputs are compatible with both CMOS and TTL voltage levels, making the IC easy to interface with microcontrollers and digital logic circuits.
  • Floating High-Side Driver: The high-side driver can be floated up to 600V, making it suitable for high-voltage applications.

Specifications

  • Supply Voltage (Vcc): 10V to 20V
  • High-Side Floating Supply Voltage (Vbs): Up to 600V
  • Gate Drive Output Current: 210 mA (source), 360 mA (sink)
  • Propagation Delay: 120 ns (typical)
  • Logic Input Threshold: CMOS/TTL compatible
  • Operating Temperature Range: -40°C to +125°C
  • Package: 8-pin DIP

Applications

  • Motor Drives: Used for driving the high-side and low-side MOSFETs or IGBTs in motor control circuits, such as in brushless DC motors or induction motors.
  • Inverters: Suitable for driving the switches in inverter circuits used in applications like uninterruptible power supplies (UPS), solar inverters, and variable frequency drives.
  • DC-DC Converters: Ideal for use in synchronous rectification or other high-efficiency DC-DC converter circuits.
  • Half-Bridge Circuits: Essential for half-bridge configurations in power electronics, enabling efficient switching and control.
  • High-Voltage Power Supplies: Applied in high-voltage power supply circuits where robust and reliable switching is required.
