Description
IR1168STRPBF is a power-management IC from Infineon/International Rectifier (IR1168 family). The STRPBF suffix means Tape & Reel packaging and Pb-free (RoHS compliant). The device is a high-side load switch/power-gating controller used to switch DC rails in embedded and automotive electronics. It typically includes protective and control features such as overcurrent/short-circuit protection, undervoltage lockout, and thermal shutdown, and is designed to drive external FETs or loads depending on the variant. Exact functions, input/output ranges, current limit, and timing vary by part, so the precise specifications are in the IR1168 datasheet. For application notes, recommended layouts, and part selection, consult Infineon’s datasheet and product pages.
Features
IR1168STRPBF is a dual-channel high-side/low-side gate driver (half-bridge) with bootstrap operation. Key features:
- Independent HS and LS gate outputs with fast drive capability
- Bootstrap high-side supply and internal charge pump
- Logic inputs compatible with standard CMOS/TTL levels (3.3–5 V)
- UVLO and undervoltage protection on both channels
- Dead-time control and cross-conduction/shoot-through protection
- Fault reporting/diagnostic flag with latch
- Overcurrent/short-circuit protection and thermal protection
- Pb-free STRPBF packaging
Designed for motor drive, power switching, and similar applications requiring reliable gate drive performance.
