What are the key features of PTLIN1021DRBRQ1?
- ISO 17987-4.2 compliant LIN transceiver ensures interoperability with all major automotive LIN bus networks up to 20 kbps
- INH and WAKE pins enable hardware-controlled sleep/wake cycles, reducing system current to under 10 µA in standby mode
- AEC-Q100 qualified for operation from -40°C to +125°C, ensuring reliable performance in harsh automotive body-electronics environments
What is PTLIN1021DRBRQ1 used for?
The PTLIN1021DRBRQ1 is designed for automotive body-control modules, seat control units, and mirror adjusters where a low-cost single-wire LIN bus links the master controller to multiple slave nodes. Its WAKE and INH features allow the module to enter a deep-sleep state and wake on bus activity, reducing quiescent current drain on the vehicle battery. The device also fits HVAC blend-door actuators and door-lock controllers that require a compact 8-pin SON footprint and robust 27 V bus-voltage tolerance.

Frequently Asked Questions
What maximum data rate does the PTLIN1021DRBRQ1 support on the LIN bus?
The PTLIN1021DRBRQ1 supports LIN bus communication at data rates up to 20 kbps, which is the standard rate defined by ISO 17987-4.2 for automotive sub-network applications such as seat adjustment and window-lift control.
How does the INH pin help reduce battery drain in a parked vehicle?
The INH pin drives an external voltage regulator into shutdown when the LIN node is idle, cutting the regulator's quiescent current. Combined with the transceiver's own standby current below 10 µA, this keeps the total node current low enough to prevent excessive battery drain over multi-day parking periods.
What supply voltage range is the PTLIN1021DRBRQ1 designed to withstand in automotive applications?
The device operates across a supply range of 5 V to 27 V and tolerates bus voltage transients up to 40 V, covering the 12 V nominal automotive battery with ample headroom for load-dump and cold-crank conditions typical of 12 V vehicle electrical systems.
Which automotive temperature grade does the PTLIN1021DRBRQ1 meet, and what does that mean for installation locations?
The PTLIN1021DRBRQ1 meets AEC-Q100 Grade 1, qualifying it for operation from -40°C to +125°C—sufficient for under-dash and door-module installations where ambient temperatures can reach 85°C to 105°C in summer-park conditions.
