- **Package:** SOIC-8  

**Descriptions:**  
The IR21531STRPBF is a high- and low-side gate driver IC with an integrated programmable oscillator. It is designed for driving MOSFETs and IGBTs in half-bridge and full-bridge configurations. The device includes under-voltage lockout (UVLO) protection for both high- and low-side drivers, ensuring safe operation.  

**Features:**  
- Integrated programmable oscillator  
- Adjustable dead time for shoot-through prevention  
- Under-voltage lockout (UVLO) protection  
- TTL/CMOS-compatible input logic  
- High noise immunity  
- Matched propagation delays for both channels  
- Pb-free and RoHS compliant
