Description

  • The IR2112 is a dual high-side and low-side driver IC available in a DIP-14 package.
  • It is ideal for driving N-channel MOSFETs or IGBTs in bridge configurations.
  • The IC features integrated bootstrap circuitry, which facilitates the generation of the gate drive voltage for the high-side transistor.
  • The IR2112 is designed to operate at high voltages, making it suitable for a wide range of power electronics applications.

Features

  • Floating Channel: Can be used to drive an N-channel power MOSFET or IGBT in the high-side configuration with a voltage range up to 600V.
  • Gate Drive Supply Range: Operates between 10V and 20V, ensuring compatibility with standard MOSFETs and IGBTs.
  • Undervoltage Lockout (UVLO): Both high-side and low-side drivers are protected against low voltage conditions, ensuring safe operation.
  • Integrated Bootstrap Diode: Simplifies circuit design by reducing the need for external components to generate the high-side drive voltage.
  • Dead-Time Control: Adjustable dead time between high-side and low-side switches to prevent shoot-through (cross-conduction).
  • Fast Switching: Propagation delays are typically 120 ns, enabling high-frequency operation.
  • CMOS and LSTTL Compatible Input: Compatible with standard logic levels, allowing for easy interfacing with microcontrollers and DSPs.
  • Latch-Up Protection: Prevents latch-up conditions in high-power operations, enhancing reliability.
  • Separate Logic and Power Ground Pins: Improves noise immunity and simplifies circuit layout.

Specifications

  • Supply Voltage (Vcc): 10V to 20V
  • Output Current: 200 mA (Source), 420 mA (Sink)
  • High-Side Floating Supply Absolute Maximum Voltage: 600V
  • Logic Input Voltage: 5V compatible (typical for TTL and CMOS logic)
  • Propagation Delay: 120 ns (typical)
  • Dead Time: Programmable via an external resistor, typically 50 ns to 500 ns
  • Operating Temperature Range: -40°C to 125°C
  • Package Type: DIP-14 (Dual In-line Package with 14 pins)
  • Bootstrap Voltage (Vbs): Up to 20V
  • Dead-Time Control Pin: Allows customization of dead time between switching transistors.
  • Output Voltage: Low side: 0V to Vcc; High side: Vb to Vs

Applications

  • Motor control (including BLDC and AC motor drives)
  • DC-DC converters and power inverters
  • Inductive heating and welding systems
  • Half-bridge and full-bridge converters
  • Solar inverters
  • Uninterruptible power supplies (UPS)
  • Switching power supplies (SMPS)
