Product details

Overview

TLE7824GXUMA1 from Infineon Technologies is an automotive System Basis Chip (SBC) with integrated 8-bit 8051-compatible MCU (24 kB Flash, 256 B RAM), dual low-side switches (1.5 A each), high-side LED driver, Hall sensor supply (5 V/100 mA), 5 wake-up inputs, LIN 2.0 transceiver, and 10-bit ADC. It operates from -40 °C to 150 °C in PG-DSO-28-38 package and targets body control modules requiring consolidated power, communication, and actuation.

For engineers reviewing the TLE7824GXUMA1 datasheet, TLE7824GXUMA1 pinout, TLE7824GXUMA1 application, or TLE7824GXUMA1 equivalent, key selection criteria include LIN bus integration, dual low-side switch current rating, Hall supply regulation accuracy, wake-up input voltage thresholds, and MCU debug support via JTAG.

Technical Context

The device integrates a multi-chip module combining an XC885-based 8-bit microcontroller and analog SBC functions on a single die. The SBC provides regulated 5 V (VCC, 150 mA) and 2.5 V (VDDC, 50 mA) supplies, LIN physical layer compliant with ISO 9141 and LIN spec 2.0, and five high-voltage wake-up inputs (12–27 V threshold range).

Its dual low-side switches feature overtemperature and short-circuit protection with current limiting at 1.5 A (typical), while the HS-LED output supports PWM dimming via MON5 pin sharing. The 10-bit ADC measures battery voltage (VBAT_SENSE) and temperature with internal reference (VAREF).

Key Specifications

Parameter	Value and Actual Design Meaning
MCU Core	8051-compatible, 24 kB Flash for firmware + data storage, enabling standalone control without external program memory
Low-Side Switches	2×, 1.5 A continuous current per channel, integrated current limiting and thermal shutdown for relay driving
LIN Transceiver	ISO 9141-2 & LIN 2.0 compliant, supports dominant/recessive bus states and automatic wake-up on LIN frame
Hall Supply Output	SUPPLY pin delivers regulated 5 V ±3 % at up to 100 mA, optimized for TLE4966-class Hall sensors
Wake-Up Inputs	5× MONx pins, detect 12–27 V signals with hysteresis, enabling sleep-mode wake via external switches or sensors
ADC Resolution	10-bit SAR converter with VAREF reference, used for battery monitoring (VBAT_SENSE) and on-die temperature sensing
Operating Temp	-40 °C to +150 °C junction temperature, qualified per AEC-Q100 Grade 0 for under-hood automotive use

Pinout & Package

Package: PG-DSO-28-38 (28-pin exposed pad SOIC, 15.6 mm × 10.5 mm, 1.27 mm pitch, RoHS-compliant green package).

Pin/Terminal	Circuit Role	Design Meaning
LS1 / LS2	Dual Low-Side Switch Outputs	Open-drain NMOS outputs rated 1.5 A each; require external flyback diodes for inductive loads like relays
MON1–MON4 / MON5/HS_LED	Wake-Up Inputs / Shared LED Driver	High-voltage digital inputs (12–27 V); MON5 doubles as PWM-controllable high-side LED driver output
VCC / VDDC	Regulated Power Outputs	VCC = 5 V @ 150 mA (system logic), VDDC = 2.5 V @ 50 mA (MCU core); both require local ceramic decoupling
LIN / TxD / RxD	LIN Bus Interface	LIN pin connects to bus line; TxD/RxD are internal MCU UART signals routed to LIN transceiver logic
SPI (DI/DO/CLK/CSN)	Serial Configuration Interface	16-bit SPI port for configuring SBC registers, reading diagnostics, and controlling switch states
P0.x / P2.x / RESET	MCU GPIOs & Reset Signal	General-purpose I/Os with capture/PWM/JTAG functions; RESET is active-low SBC output and MCU input

Key Features

Feature	Design Value
Integrated LIN 2.0 Transceiver	Eliminates need for discrete LIN PHY; supports automatic wake-up and bus error detection per ISO 17987
Dual Protected Low-Side Switches	On-chip current limiting, thermal shutdown, and open-load detection enable robust relay control without external protection
Hall Sensor Supply (SUPPLY)	Stable 5 V ±3 % output with 100 mA capability ensures accurate operation of magnetic position sensors
Programmable Window Watchdog	Configurable timeout and window violation detection prevents MCU lockup in safety-critical body electronics
JTAG Debug Support	On-chip OCDS enables real-time debugging, flash programming, and boundary scan without external emulator hardware

Use Scenario: Centralized control of door locks, window lifts, and interior lighting in modern vehicles.

IC Role / Device Role / Timing Role: SBC + MCU performs system supervision, LIN communication with door modules, and drives relays/LEDs via integrated switches.

Use Value: Reduces BOM count by consolidating LIN PHY, power regulation, and actuation into one PG-DSO-28 package.

Use Scenario: Monitoring Hall-effect sensors on seat track motors and adjusting position via motor drivers.

IC Role / Device Role / Timing Role: SUPPLY pin powers Hall sensors; ADC reads position feedback; LS1/LS2 control H-bridge direction logic.

Roof Module Control

Trunk Release Actuation

Use Scenario: Managing sunroof motor, ambient lighting, and rain sensor interface in overhead console units.

IC Role / Device Role / Timing Role: MON inputs detect switch presses; HS-LED drives status LEDs; LIN reports status to BCM.

Use Value: MON5/HS_LED pin sharing allows switch detection and visual feedback using same terminal-saving PCB space.

Use Scenario: Activating trunk latch solenoid upon valid LIN command or mechanical release switch press.

IC Role / Device Role / Timing Role: LS2 drives 12 V solenoid load; wake-up inputs monitor trunk switch; watchdog ensures fail-safe deactivation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar automotive SBC + MCU applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE7810G	No embedded MCU; SBC-only with single low-side switch, no HS-LED, smaller Flash footprint not applicable	Limited to simple peripheral control without local decision-making; requires external microcontroller	Select when only basic power/communication functions are needed and MCU functionality is handled externally
TLF35584ESV50	32-bit ARM Cortex-M0+ MCU (128 kB Flash), triple low-side switches, ASIL-B capable, no Hall supply output	Targeted at higher-safety domains (e.g., ADAS power management); lacks dedicated Hall sensor regulator	Select for ASIL-B systems requiring higher compute performance and functional safety certification

Compared with TLE7824GXUMA1, TLE7810G reduces integration but increases system complexity with external MCU, while TLF35584ESV50 raises safety compliance and processing capability at the cost of Hall sensor support and pin compatibility.

FAQ

What is the maximum continuous current rating for the low-side switches?

The TLE7824GXUMA1's LS1 and LS2 outputs each support 1.5 A continuous current at TJ ≤ 125 °C, with built-in current limiting that activates above 2.2 A (typical) and thermal shutdown at 175 °C. Derating applies above 100 °C ambient per datasheet Figure 25.

Does the device support LIN firmware updates over the bus?

Yes - the integrated LIN bootloader in the 12 kB boot ROM enables field firmware updates via LIN Fast Mode without requiring external programming hardware. The process uses standardized UDS services (0x31/0x34/0x36) and requires host-side LIN stack support for diagnostic session control.

Can the MON5 pin be used simultaneously as wake-up input and LED driver?

No - MON5 and HS-LED share the same physical pin and operate in mutually exclusive modes: configured as wake-up input in SBC standby, or as high-side PWM output in active mode. Mode switching is controlled via SPI register writes and cannot occur concurrently.

What is the accuracy of the internal temperature sensor?

The on-die temperature sensor feeds the 10-bit ADC with ±3.5 °C accuracy over -40 °C to +150 °C, calibrated at two points (25 °C and 125 °C) during production. Raw ADC codes require linear interpolation using coefficients stored in Flash for full-range compensation.
