Overview
The S-19680BAAH-K8T2U is a high-side power switch IC from ABLIC, designed for automotive applications. It features a single P-channel output capable of delivering up to 50mA load current with an on-resistance of 1.1 Ohms. The device operates within a supply voltage range of up to 10V and is housed in an 8-pin TMSOP package. It holds AEC-Q100 qualification, ensuring reliability in harsh environments.
Feature Summary
- Integrated high-side switching capability for load control
- Automotive-grade reliability with AEC-Q100 certification
- Compact surface-mount packaging for space-constrained designs
Applications
- GNSS antenna amplifier power supply
- ADAS domain controller peripheral switching
- Automotive sensor interface circuits
Procurement Notes
Verify the specific suffix K8T2U corresponds to the required tape and reel quantity and marking configuration. Confirm that the 1.1 Ohm on-resistance meets the thermal requirements for the intended load current. Ensure the 10V maximum supply rating aligns with the system bus voltage. Check for any specific ordering restrictions or lead time variations associated with this automotive-qualified part number.
Selection Notes
Select this component when a compact, automotive-qualified high-side switch is needed for low-current loads such as antenna amplifiers. The P-channel configuration simplifies gate drive requirements compared to N-channel alternatives. Consider the 1.1 Ohm resistance for voltage drop calculations. Verify compatibility with the target PCB footprint for the 8-TMSOP package during the design phase.
Part Context
This part belongs to the S-19680 series of power distribution switches from ABLIC. These ICs are specifically engineered for automotive electronics, offering protection features and diagnostic capabilities. The series supports various load currents and configurations, with the BAAH variant providing a balance of performance and size for modern vehicle electronic systems.
Replacement Considerations
Direct substitutes include other ABLIC S-19680 series variants with compatible pinouts and electrical characteristics. Cross-manufacturer replacements must match the 10V supply limit, 50mA current capacity, and 8-TMSOP package dimensions. Verify that alternative parts also hold AEC-Q100 qualification if automotive compliance is required.
