Типичное применение
TLF35584QKVS2XUMA2 подходит для 6 применениеs: ADAS Domain Controller, Chassis Control ECU, Electric Power Steering, Airbag and Restraint ECU, Body Control Module, Battery Management System.
ADAS Domain Controller
The TLF35584QKVS2XUMA2 is purpose-built for ADAS domain controllers requiring ASIL-D functional safety. Its integrated 3.3V main output supplies the host MCU while two independent sensor rails feed cameras and radar MMICs with low-noise power. The window and functional watchdogs validate MCU software execution at the highest integrity level. Cold-crank tolerance down to 3V ensures the ADAS controller remains alive during engine start, and the SPI interface allows dynamic reconfiguration of watchdog windows. With AEC-Q100 Grade 1 qualification and a compact LQFP-64 footprint, it is the canonical power backbone for central ADAS ECUs.
Рекомендуется
Chassis Control ECU
Chassis modules such as electronic stability control and brake-by-wire demand ASIL-D power supervision. The TLF35584QKVS2XUMA2 supplies the chassis MCU at 3.3V while its dual sensor rails feed wheel-speed and yaw-rate sensors with isolated, low-ripple power. The integrated window watchdog enforces deterministic software service timing, critical for chassis loops operating at sub-10ms cycle times. The device's 40V load-dump tolerance protects the chassis ECU from transient events on the 12V battery bus. PG-LQFP-64-18 with exposed pad simplifies thermal dissipation in sealed underbody modules.
Рекомендуется
Electric Power Steering
Electric power steering (EPS) systems require ASIL-D power management to ensure the steering assist remains under control during fault conditions. The TLF35584QKVS2XUMA2 provides the 3.3V logic rail for the EPS MCU plus isolated sensor supplies for torque and angle sensors, with the integrated safety mechanisms monitoring both. The ROT (Reset Output) signal triggers a safe-state shutdown of the steering controller if the watchdog is not serviced, preventing unintended steering torque. AEC-Q100 Grade 1 qualification supports underhood ambient temperatures, and the LQFP-64 exposed pad keeps junction temperature within limits during high-load EPS operation.
Рекомендуется
Airbag and Restraint ECU
Airbag ECUs require ASIL-D power management because deployment decisions depend on a single MCU's correct operation. The TLF35584QKVS2XUMA2 supplies this MCU at 3.3V with redundant window and functional watchdog supervision that meets the highest ISO 26262 integrity level. The integrated fault output (ROT) signals the airbag squib driver to inhibit deployment during MCU malfunction, a critical safety function. The device's 3V cold-crank tolerance ensures crash sensing remains armed during engine start, and AEC-Q100 Grade 1 qualification supports the harsh thermal environment of airbag modules mounted under the dash.
Рекомендуется
Body Control Module
Body control modules (BCMs) increasingly demand ASIL-B or ASIL-D power supervision as they integrate more safety-relevant lighting and access functions. The TLF35584QKVS2XUMA2 provides a 3.3V main rail plus two sensor supplies in a single LQFP-64 package, reducing BOM count versus discrete LDOs. The SPI-configurable window watchdog allows OEMs to tune watchdog timing per platform, and the integrated OV/UV/OT protections simplify the BCM safety case. With 40V load-dump tolerance and AEC-Q100 Grade 1, the device is well suited to centralized body controllers distributed throughout the vehicle harness.
Рекомендуется
Battery Management System
12V and 48V battery management systems (BMS) require a robust, ASIL-D capable PMIC for the supervising MCU and cell-monitoring AFEs. The TLF35584QKVS2XUMA2 supplies the BMS MCU at 3.3V and provides two independent sensor rails for current and temperature sensing with low-noise, low-drift power. The integrated window and functional watchdogs ensure the BMS MCU executes its safety checks within deterministic timing, critical for cell-balancing decisions. The device's wide input range supports direct connection to the battery bus, and the exposed-pad LQFP-64 package simplifies thermal management in underbody-mounted BMS housings.

Заметки по проектированию
The PG-LQFP-64-18 package uses an exposed thermal pad (pin 65) that must be soldered to a copper pour of at least 1 square inch on the top layer for thermal dissipation. Estimated: at 500mA total load and VIN=12V, VOUT=3.3V, the dissipation is approximately 4.35W; without thermal relief, junction temperature can exceed 150C in a sealed module. Use multi-layer thermal vias under the pad per IPC-2152 to conduct heat to inner copper planes.
Follow Infineon's reference layout for the LQFP-64 footprint. Place input capacitors (10uF X7R minimum) within 5mm of the VSUP pins, and route the SW switching node with a 0.5mm minimum trace and a 0.8mm keepout to adjacent traces to avoid noise coupling. The bootstrap capacitor (BST to SW) must be a 100nF ceramic placed within 3mm of the BST pin. GND and PGND must be connected at a single star point under the IC exposed pad.
The TLF35584QKVS2XUMA2 ROT (Reset Output) pin must be pulled up to VCC3V3 with a 10kohm resistor; if left floating, the MCU may interpret noise as a valid reset. Do not connect the TEST pin (pin 31) to anything other than ground in production - floating TEST pins can latch the device into a test mode that disables safety functions. The SPI SDO pin requires a pull-up if multiple devices share the bus; verify CS timing meets the datasheet minimum high time before initiating a new transaction.
