The IR2125S is a high-speed power MOSFET and IGBT driver manufactured by International Rectifier (IR). Below are the specifications, descriptions, and features based on the manufacturer's data:

Manufacturer: International Rectifier (IR)

Specifications:

• Output Current: 0.5A (source/sink)
• Supply Voltage (VCC): 10V to 20V
• Logic Input Voltage (VIN): 3.3V, 5V, and 15V compatible
• Propagation Delay (tP): 120ns (typical)
• Rise/Fall Time (tR/tF): 35ns / 25ns (typical)
• Operating Temperature Range: -40°C to +125°C
• Package: 8-lead SOIC

Descriptions:

• The IR2125S is a high-voltage, high-speed MOSFET and IGBT driver with independent high- and low-side referenced output channels.
• It is designed for applications requiring high noise immunity and fast switching performance.
• The device integrates a high-voltage level shifter, under-voltage lockout (UVLO), and shoot-through protection.

Features:

• Floating Channel Design: Allows driving high-side N-channel MOSFETs or IGBTs.
• Compatible with CMOS/LSTTL Outputs: Supports 3.3V, 5V, and 15V logic inputs.
• Under-Voltage Lockout (UVLO): Ensures proper operation by disabling outputs if supply voltage is insufficient.
• Matched Propagation Delay: Minimizes dead time in half-bridge applications.
• Shoot-Through Protection: Prevents cross-conduction in bridge configurations.
• Low Power Consumption: Optimized for efficiency in high-frequency switching applications.
