TLE92633BQXXUMA2 Overview
A System Basis Chip (SBC) is a highly integrated power management and communication IC for automotive ECUs that combines a voltage regulator with transceivers for in-vehicle networking, typically CAN and LIN. Within the broader hierarchy, SBCs sit above standalone LDOs and standalone CAN/LIN transceivers, and below complete Automotive Power Management ICs (PMICs); by consolidating these functions on one die, SBCs reduce PCB area, quiescent current, and BOM cost in body controllers, gateways, and sensor nodes.
The TLE92633BQXXUMA2 features a 5V LDO (and a 3.3V LDO variant in the family), high-speed CAN FD with bus wake-up capability, two LIN transceivers, an integrated watchdog timer with multiple window modes, and a typical quiescent current of approximately 3.5mA. The PG-VQFN-48-79 exposed-pad package enables robust thermal performance for the harsh automotive under-hood environment and supports surface-mount manufacturing flows.
Typical applications include automotive body control modules (BCMs), central gateway ECUs, HVAC controllers, seat and door zone modules, and sensor/ECU nodes that communicate over CAN FD or LIN. The wide 3V to 28V input range tolerates load-dump and jump-start transients typical of 12V automotive power nets, and the watchdog supports ASIL-rated system architectures.
When designing with this SBC, follow Infineon's PCB layout guidance for the exposed pad to keep junction temperature within the -40C to +150C automotive range, and choose the appropriate LDO variant (5V or 3.3V) for the downstream microcontroller core voltage.

Typical Applications
TLE92633BQXXUMA2 is suitable for 6 applications: Automotive Body Control Module (BCM), Central Gateway ECU, HVAC Control Module, Door/Seat Zone Module, Sensor/ECU Node (LIN Slave), Automotive Lighting Module (LIN-driven).
Automotive Body Control Module (BCM)
The TLE92633BQXXUMA2 is well-suited for 12V automotive body control modules because it consolidates a 5V LDO, a 3.3V LDO, and CAN FD plus dual LIN transceivers into a single PG-VQFN-48-79 chip. This reduces the BCM PCB area by approximately 30 percent versus discrete regulator-plus-transceiver solutions, and the 3V to 28V input range handles 12V cranking and load-dump events per ISO 7637. The integrated watchdog with multiple window modes supports ASIL-rated system architectures used in BCMs.
Recommended
Central Gateway ECU
In automotive central gateway ECUs that bridge CAN FD and LIN subnetworks, the TLE92633BQXXUMA2 provides both network interfaces plus the microcontroller power rails from a single 12V battery source. The CAN FD transceiver supports bit rates up to 5 Mbit/s for high-bandwidth gateway traffic, while the dual LIN transceivers serve body and comfort sub-buses. The integrated 5V/3.3V LDOs power the gateway MCU directly, eliminating external PMICs and reducing BOM cost.
Recommended
HVAC Control Module
The TLE92633BQXXUMA2 powers HVAC control modules that communicate with the vehicle body network over CAN FD or LIN. Its -40C to +150C junction temperature range handles the under-dash thermal environment, while the integrated watchdog supports fault recovery for safety-relevant HVAC functions. The 3.5mA typical quiescent current keeps battery drain low during parked-vehicle states, important for always-on HVAC features.
Recommended
Door/Seat Zone Module
Door and seat zone modules require compact integration of LIN communication, sensor power, and actuator drive logic, all powered from the 12V battery. The TLE92633BQXXUMA2 fits this role with its dual LIN channels and dual LDO outputs, occupying less than 50 mm^2 of PCB area including passives. The PG-VQFN-48-79 package's exposed pad enables sustained operation in the door cavity's elevated ambient temperatures.
Recommended
Sensor/ECU Node (LIN Slave)
For LIN-slave sensor nodes (e.g., rain-light, ambient temperature, or occupancy sensors), the TLE92633BQXXUMA2 provides the LIN physical layer plus 5V/3.3V rails to power the sensor MCU and analog front end from the 12V vehicle bus. Its bus-wake capability allows the sensor to wake the rest of the network when needed, supporting partial-networking strategies that reduce quiescent drain across the vehicle.
Recommended
Automotive Lighting Module (LIN-driven)
LED headlamp or tail-lamp modules that communicate over LIN benefit from the TLE92633BQXXUMA2's combined power and communications integration. The 5V LDO can supply a companion LED driver (e.g., ILD8150EXUMA1), while the 3.3V LDO powers the lighting MCU. The 3V to 28V input range tolerates the load-dump pulses that occur on the 12V battery during alternator-load switching events.

Key Differentiators
- Dual LDO outputs (5V + 3.3V) in single SBC (vs TLE9263BQX)
- Dual LIN transceivers for body-network zoning (vs TLE92623BQXXUMA2)
- Same-package mid-range+ SBC family scalability (vs TLE92783BQX)
Design Notes
Solder the exposed thermal pad of the PG-VQFN-48-79 package to a continuous PCB land with at least 16 thermal vias to the inner ground plane. At full CAN FD bus-load and continuous LDO current, internal dissipation can reach approximately 0.7W; without thermal vias, the junction-to-ambient resistance rises above 50 C/W and can exceed the -40C to +150C automotive rating in underhood environments.
Keep the CANH/CANL traces as a differential pair with 100-ohm impedance, and place a common-mode choke within 5 mm of the IC pins to meet automotive EMC requirements per IEC 61967. Decouple VS with a 100nF ceramic close to the IC plus a 10uF electrolytic bulk capacitor within 10 mm to absorb load-dump energy. Decouple each LDO output with a 2.2uF X7R ceramic.
Do not operate the TLE92633BQXXUMA2 below 3V on VS without ensuring the 5V LDO output has dropped out first; the integrated reset circuit may assert unexpectedly during slow VBAT ramps. For LIN bus wake-up to function, the WK pin must be configured per the Infineon TLE9263 family datasheet; a floating WK pin prevents bus wake from reaching the MCU.
Route the CAN and LIN signals on the top layer with a continuous ground reference plane below; avoid routing these traces across plane splits which can increase common-mode emissions. Place the IC's exposed pad on a top-layer copper pour that is stitch-bonded to the inner ground plane with a 4x4 via grid to minimize thermal and EMI impedance simultaneously.
Compliance Information
RoHS compliant per distributor listings. AEC-Q100 qualified for automotive use; the -Q suffix in ordering codes indicates the automotive-qualified test flow per Infineon's product naming convention.
