Overview
The ATA6140-TBQY is an automotive-grade dual-output flasher controller manufactured by Microchip Technology. Designed for driving automotive lighting loads, it features a supply voltage range of 8V to 33V and supports an operating temperature from -40°C to 105°C. The device provides an output current capability of 170mA per channel with a supply current of 8mA. It is housed in a 16-SOP (SOIC) package with a width of 3.90mm.
Feature Summary
- Automotive-grade reliability designed for vehicle lighting applications
- Dual output configuration for independent control of lighting loads
- Robust electrical specifications supporting wide voltage and temperature ranges
Applications
- Automotive exterior lighting systems
- Vehicle turn signal circuits
- Headlight flasher modules
Procurement Notes
Verify the specific suffix TBQY against official Microchip documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with existing PCB footprints for the 16-SOP form factor. Cross-reference the datasheet for absolute maximum ratings to prevent overvoltage or thermal stress during integration.
Selection Notes
Select this component when dual-channel flasher functionality is required within automotive environments. Consider the 170mA output limit for load sizing and the 8V-33V input range for system power architecture. Validate that the 16-SOP package fits the assembly constraints and thermal management requirements of the target design.
Part Context
This part belongs to the ATA6140 family of flash controllers. It serves as a specialized driver for automotive lighting, distinct from general-purpose logic ICs. The device integrates necessary control logic to manage flashing patterns for vehicle safety lights without requiring external complex circuitry.
Replacement Considerations
Consult Microchip's official change notification documents for direct pin-to-pin replacements. Verify that any substitute maintains the same automotive qualification standards and output current capabilities.
