What are the key features of PTLIN10285DRQ1?
- AEC-Q100 Grade 1 qualified for automotive reliability (-40°C to +125°C)
- Integrated 85 mA LDO regulator supplying MCU or sensor load directly
- LIN 2.0, 2.1, 2.2A, and SAE J2602 protocol compliance
- 5 V to 30 V operating supply range tolerating 40 V load-dump transients
- 8-pin SOIC package enabling single-chip LIN node with minimal BOM
- Wake-up capability from LIN bus for low-power sleep modes
What is PTLIN10285DRQ1 used for?
PTLIN10285DRQ1 is used in automotive body-control modules, seat-motor controllers, mirror-adjustment nodes, and HVAC flap-actuator sub-nodes where a LIN bus slave must supply its own logic power from the 12 V vehicle rail. Its integrated LDO eliminates an external regulator, reducing component count in space-constrained door-module PCBs and sensor clusters.

Frequently Asked Questions
What AEC-Q qualification does PTLIN10285DRQ1 carry, and what operating temperature range does that imply for underhood automotive use?
PTLIN10285DRQ1 is qualified to AEC-Q100 Grade 1, which covers an ambient operating temperature range of -40°C to +125°C. This qualification level is required for components mounted in or near the engine compartment, making the device suitable for transmission sensors, actuator nodes, and other high-temperature automotive sub-systems.
What load current can the integrated LDO regulator in PTLIN10285DRQ1 supply to an external MCU?
The integrated LDO delivers up to 85 mA output current from the 12 V vehicle supply, which is enough to power a typical low-power automotive MCU such as a PIC or STM8 running at a few MHz plus a few passive sensors. This eliminates a discrete regulator, reducing the LIN node BOM by at least 1 IC and several passives.
Which LIN protocol versions does PTLIN10285DRQ1 support, and does it interoperate with older LIN 1.3 masters on the same bus?
PTLIN10285DRQ1 supports LIN 2.0, 2.1, 2.2A, and SAE J2602, all of which use the same physical layer as LIN 1.x. The transceiver's physical-layer signaling is backward-compatible, so a LIN 1.3 master can communicate with a node using PTLIN10285DRQ1, although the 1.3 checksum format must be handled in firmware.
How does PTLIN10285DRQ1 protect against automotive load-dump transients on the 12 V supply line?
The device tolerates supply voltages up to 40 V on the VSUP pin, covering the ISO 7637 load-dump transient profile that can reach 40 V for up to 400 ms. This built-in robustness removes the need for an external transient-voltage suppressor on many automotive body-module designs, simplifying the protection network.
