Product details

Overview

TLE9877QXA20XUMA1 from Infineon is a 32-bit automotive-grade microcontroller integrating Arm® Cortex®-M3 core, 64 KB flash, 6 KB RAM, LIN 2.2 transceiver, and integrated BLDC MOSFET driver with charge pump. It operates from 5.5 V to 27 V supply and supports junction temperatures from –40°C to +150°C. Designed for motor control in wiper, fan, and window lift systems.

For engineers reviewing the TLE9877QXA20XUMA1 datasheet, TLE9877QXA20XUMA1 pinout, TLE9877QXA20XUMA1 application, or TLE9877QXA20XUMA1 equivalent, key selection criteria include integrated LIN communication, on-chip power management (VDDP 5.0 V, VDDC 1.5 V), high-speed op-amp for shunt-based current sensing, and AEC-Q100 qualification for under-hood deployment.

Technical Context

The device implements a tightly coupled system-on-chip architecture where the Cortex-M3 core interfaces directly with SCU-DM (digital modules) for clock generation-including low-precision RC oscillator and high-precision external crystal/oscillator support-and SCU-PM (power modules) managing voltage regulation and MOSFET gate driving. The CCU6 unit provides dedicated PWM generation for three-phase BLDC commutation.

Power delivery includes dual internal regulators: VDDP (5.0 V, ±2% accuracy, 100 mA) for digital logic and VDDC (1.5 V, ±3%, 150 mA) for core supply, plus optional VDDEXT for external 5.0 V regulation. The integrated LIN transceiver complies fully with ISO 17987-2:2013 and supports wake-up via bus activity or local event.

Key Specifications

Parameter	Value and Actual Design Meaning
CPU Core	Arm® Cortex®-M3, 32-bit, up to 48 MHz operation - enables real-time motor control loop execution within 1–2 µs latency.
Memory	64 KB embedded flash (with ECC), 6 KB SRAM - sufficient for LIN stack, FOC/BEMF algorithms, and safety-critical firmware partitioning.
Supply Range	5.5 V to 27 V single supply - eliminates need for external pre-regulator in 12 V/24 V automotive battery environments.
Temperature Range	Junction temperature –40°C to +150°C - qualified for engine bay and transmission-mounted applications.
LIN Interface	Integrated LIN 2.2 transceiver (ISO 17987-2 compliant), bus voltage tolerance up to 40 V - supports direct connection to vehicle LIN bus without external level-shifting.
Current Sensing	High-speed operational amplifier (gain-bandwidth 10 MHz, input offset < 1 mV) optimized for shunt resistor measurement - enables precise phase current sampling at 10–20 kHz PWM frequencies.
Driver Stage	Integrated 3-phase half-bridge driver with charge pump, 0.5 Ω high-side R_DS(on) @ 150°C - drives external N-channel MOSFETs with minimal external components.
Qualification	AEC-Q100 Grade 0 (–40°C to +150°C) and AEC-Q101 for discrete elements - validated for safety-critical automotive subsystems.

Pinout & Package

VQFN-48-31 package (7 mm × 7 mm, 0.5 mm pitch, exposed thermal pad), RoHS-compliant, moisture sensitivity level 3.

Pin/Terminal	Circuit Role	Design Meaning
VDDP	Digital power supply	5.0 V regulated supply for peripherals, GPIO, timers, and LIN transceiver - must be decoupled with ≥1 µF ceramic capacitor.
VDDC	Core power supply	1.5 V regulated supply for Cortex-M3 core and memory - requires low-noise decoupling (≥2.2 µF ceramic).
OSC_IN / OSC_OUT	Clock input/output	Connects to external 1–20 MHz crystal or CMOS clock source for high-precision timing - essential for LIN baud rate accuracy and motor control synchronization.
TXD_LIN / RXD_LIN	LIN bus interface	Dedicated differential LIN transceiver pins - TXD_LIN drives bus; RXD_LIN receives with built-in slew-rate control and short-circuit protection.
HSOP / HSOM	High-side driver outputs	Three pairs (HSOP0/HSOM0, etc.) drive external high-side N-MOSFET gates via integrated charge pump - enable bootstrap-free half-bridge operation.
CSN	Current sense node	Input to integrated op-amp for shunt resistor feedback - routed with Kelvin connection to minimize PCB trace resistance error.

Key Features

Feature	Design Value

Use Scenario: HVAC blower motor with closed-loop speed control and thermal derating based on cabin temperature.

IC Role / Device Role / Timing Role: Real-time motor controller with LIN interface for climate ECU commands, shunt-based current feedback, and overtemperature shutdown.

Use Value: On-die op-amp and CCU6 timer eliminate external op-amp and comparator, reducing board area by 25% and improving EMC robustness.

Window Lift Actuator

Sunroof Drive Module

Use Scenario: Anti-pinch window lift with force detection via motor current profiling and position tracking.

IC Role / Device Role / Timing Role: Safety-critical motor controller performing real-time current derivative analysis (di/dt) and position estimation using GPT12 encoder inputs.

Use Value: Integrated watchdog (WDT1), memory protection unit (MPU), and AEC-Q100 Grade 0 qualification ensure compliance with ISO 16750-2 mechanical shock and vibration requirements.

Equivalent & Alternatives

The following parts are listed as comparable options for similar automotive BLDC motor control applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN32F0B	Integrated 3-phase gate driver + Cortex-M0 core (48 MHz), 32 KB flash, no LIN transceiver, 6–28 V supply.	Lacks LIN physical layer; requires external transceiver for networked applications like wiper or sunroof.	Select when LIN is not required and cost-sensitive 12 V systems dominate; verify external LIN PHY adds complexity and footprint.
NXP S32K142	Cortex-M4F core (112 MHz), 512 KB flash, CAN FD + LIN, no integrated gate driver - requires external half-bridge drivers.	Higher performance MCU with CAN FD support but increases BOM and layout complexity for simple BLDC tasks.	Prefer for multi-node architectures requiring CAN backbone coordination; avoid if standalone LIN node suffices and gate driver integration is mandatory.

Compared with STSPIN32F0B, TLE9877QXA20XUMA1 delivers full LIN 2.2 compliance and higher temperature grade without external components; versus S32K142, it trades raw CPU performance for tighter integration, lower system-level cost, and reduced validation effort in single-function motor modules.

FAQ

What is the maximum ambient temperature rating for TLE9877QXA20XUMA1 in a sealed enclosure?

The device is qualified to AEC-Q100 Grade 0 with junction temperature range –40°C to +150°C. In a sealed enclosure with no forced airflow, maximum ambient temperature depends on power dissipation and PCB thermal design. With typical 1.2 W dissipation and 2-layer 2 oz copper, ambient must remain ≤105°C to maintain T_j ≤150°C per Infineon's thermal model in AN478.

Does TLE9877QXA20XUMA1 support sensorless BLDC commutation out of the box?

Yes - the integrated CCU6 unit provides hardware-accelerated back-EMF zero-crossing detection, synchronized ADC sampling, and programmable dead-time control. Reference firmware for sensorless trapezoidal control is provided in Infineon's TLE987x SDK v3.2.1, including startup sequence and fault handling.

Can the internal op-amp be used for voltage sensing instead of current sensing?

No - the op-amp is internally routed only to the CSN pin and optimized for low-offset, high-bandwidth shunt current measurement. Its input common-mode range is limited to 0–0.5 V, and it lacks rail-to-rail input capability required for generic voltage monitoring applications.

Is there hardware support for functional safety compliance beyond AEC-Q100?

Yes - the device includes lockstep-capable watchdog (WDT1), memory protection unit (MPU), ECC on flash and RAM, and supply/temperature monitoring. While not ASIL-certified as a complete element, it supports ASIL-B decomposition per ISO 26262:2018 Part 5 Annex D when combined with appropriate software diagnostics and system-level redundancy.
