IR21531STR is a high-voltage, high-speed power MOSFET and IGBT driver with integrated oscillator, manufactured by Infineon Technologies.

The IR21531STR is a high-voltage, high-speed power MOSFET and IGBT driver with integrated oscillator, manufactured by Infineon Technologies.

Specifications:

  • Voltage Supply (VCC): 10V to 20V
  • Output Current (Source/Sink): 210mA / 420mA
  • Operating Frequency Range: Up to 1MHz
  • High-Side Floating Supply Voltage (VB): Up to 600V
  • Deadtime Control: Programmable (via external resistor)
  • Under-Voltage Lockout (UVLO): 8.4V (typical)
  • Temperature Range: -40°C to +125°C
  • Package: SOIC-8

Descriptions:

The IR21531STR is a self-oscillating half-bridge driver with a built-in oscillator, designed to drive N-channel power MOSFETs and IGBTs. It features high-side and low-side outputs with matched propagation delays, ensuring precise switching control. The device includes a programmable deadtime to prevent shoot-through in half-bridge configurations.

Features:

  • Integrated oscillator with adjustable frequency
  • High noise immunity
  • Matched propagation delays for both high-side and low-side outputs
  • Low power consumption
  • Programmable deadtime (50ns to 5µs)
  • Under-voltage lockout for both high-side and low-side drivers
  • CMOS Schmitt-triggered inputs with pull-down

This driver is commonly used in applications such as switch-mode power supplies (SMPS), motor control, and electronic ballasts.
