AEC-Q100 12-switch LED matrix manager, 4.5-60 V, 10-bit PWM, UART/CAN PHY, HTQFP-48
The TPS92662A-Q1 is an automotive LED matrix manager with 12 integrated bypass switches, arranged as four sub-strings of three series switches, enabling pixel-level dimming of LEDs driven by an external current source. It operates from 4.5 V to 60 V and offers programmable 10-bit PWM dimming, an 8-bit ADC, LED open/short detection and protection, a multi-drop UART interface compatible with the CAN physical layer, and EMI-mitigation features. Typical applications include adaptive driving beam headlights, glare-free high beam, and sequential turn or animated daytime running lights.

Quality & Traceability
Cerametronics is ISO 9001 certified and products are RoHS compliant, with counterfeit screening and full traceability on every shipment. A Certificate of Conformance is available on request. For allocation-sensitive or high-risk lots, independent third-party lab verification can be arranged — just flag it on your RFQ. Any lot that fails incoming inspection is quarantined and never shipped.
FAQ
Can more than 12 LEDs be controlled in one string?
Yes. Several TPS92662A-Q1 devices can be synchronized to manage strings of more than 12 LEDs.
What host interface does it use?
A multi-drop UART interface compatible with the CAN physical layer and with TPS92662-Q1 and TPS92663-Q1 devices; an external EEPROM connects over I2C.
