Product details
Overview
TLE7810GXUMA1 from Infineon Technologies is an automotive System Basis Chip (SBC) with integrated 8-bit 8051-compatible MCU (16 kB Flash, 256 B RAM), dual low-side switches (1.4 A each), high-side LED driver (40 mA), LIN 2.0 transceiver, 5× wake-up inputs, Hall sensor supply (5 V/100 mA), LDO regulator (5 V/150 mA), and 10-bit ADC. It operates from -40 °C to 150 °C and targets body control modules requiring consolidated power, communication, and actuation.
For engineers reviewing the TLE7810GXUMA1 datasheet, TLE7810GXUMA1 pinout, TLE7810GXUMA1 application, or TLE7810GXUMA1 equivalent, key selection criteria include LIN bus integration, dual relay-driving capability, Hall sensor supply regulation, wake-up input voltage tolerance (up to 28 V), and embedded MCU programmability for firmware-defined system behavior.
Technical Context
The TLE7810GXUMA1 integrates a microcontroller core and SBC functions in a single Multi-Chip-Module (MCM). Its LIN transceiver complies with ISO 9141 and LIN spec 2.0, supports dominant-mode wake-up, and features internal pull-ups on TxD and RxD. The SBC includes programmable window watchdog, overtemperature protection, and undervoltage reset generator with hysteresis.
Two independent low-side switches (LS1/LS2) support 1.4 A continuous current with short-circuit and overtemperature protection. The MON5/HS_LED pin serves dual function: high-voltage wake-up input (28 V tolerant) and high-side LED driver output (40 mA sink). The 10-bit ADC measures battery voltage (VBAT_SENSE) and temperature via internal sensor.

| VCC (Pin 23) | Main Logic Supply Output | 5 V / 150 mA LDO output; powers internal logic and external peripherals; requires local 10 µF ceramic decoupling. |
| VBAT_SENSE (Pin 26) | Battery Voltage Monitor Input | Analog input for scaled battery voltage measurement; used by internal ADC for supply supervision and diagnostics. |
| LIN (Pin 4) | LIN Bus Transceiver Line | Single-wire bidirectional interface compliant with LIN 2.0; supports slave node communication and bus wake-up. |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Body Control Module (BCM) | Seat Position Control |
|---|---|
|
Use Scenario: Centralized control of door locks, interior lighting, and window lifts in modern passenger vehicles. IC Role / Device Role / Timing Role: SBC provides power regulation, LIN communication, and relay driving; MCU executes application logic and diagnostics. Use Value: Reduces component count by integrating two low-side switches, LIN transceiver, and Hall supply-cutting board space by ~35% vs. discrete solution. |
Use Scenario: Motorized adjustment of seat position using Hall-effect sensors for feedback and relays for motor direction control. IC Role / Device Role / Timing Role: SUPPLY pin powers Hall sensors; LS1/LS2 drive H-bridge relays; ADC reads Hall position data; LIN reports status to central ECU. Use Value: Single-chip solution eliminates separate voltage regulator, LIN transceiver, and relay drivers-reducing interconnect complexity and failure points. |
| Roof Module (Sunroof/Convertibles) | Trunk/Liftgate Actuation |
|
Use Scenario: Controlled opening/closing of sunroof or convertible top with obstacle detection and position feedback. IC Role / Device Role / Timing Role: MON inputs monitor limit switches; HS_LED drives status LEDs; LIN handles command/response with body domain controller. Use Value: Wake-up inputs enable ultra-low-power standby (<10 µA); MON5/HS_LED dual function saves one GPIO and external LED driver. |
Use Scenario: Power-operated liftgate with soft-close, anti-pinch, and position sensing. IC Role / Device Role / Timing Role: LS1/LS2 control motor polarity relays; ADC monitors motor current via shunt; temperature sensor prevents thermal overload. Use Value: Integrated overtemperature and short-circuit protection avoids external monitoring circuitry-improving reliability and reducing validation effort. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive SBC with MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLF35584ESV50 | 32-bit ARM Cortex-M0+ MCU (1 MB Flash), triple watchdog, higher integration (CAN FD, multiple LDOs), no integrated low-side switches. | Targeted at higher-tier ADAS and gateway modules; lacks native relay-driving capability. | Select when CAN FD connectivity and larger code space are required; not drop-in for relay-centric designs. |
| MC33816 | 8-bit S12X MCU (64 kB Flash), LIN + SPI, dual low-side switches (1.2 A), but no Hall supply output or MON5/HS_LED dual-function pin. | Designed for entry-level body electronics; lacks dedicated Hall sensor regulator and shared wake-up/LED pin. | Choose for cost-sensitive applications where Hall supply is provided externally and LED indication is handled separately. |
Compared with TLF35584ESV50 and MC33816, the TLE7810GXUMA1 uniquely combines 16 kB Flash MCU, dual 1.4 A low-side switches, Hall supply regulator, and MON5/HS_LED pin sharing-making it optimal for compact, relay-driven body nodes where pin count and BOM minimization are critical.

FAQ
What is the maximum continuous current rating for the low-side switches?
The TLE7810GXUMA1 specifies 1.4 A continuous current per low-side switch (LS1 and LS2) under TJ ≤ 150 °C and ambient conditions per datasheet Section 11. Current derating applies above 125 °C junction temperature. Peak pulsed current capability is 2.5 A for <100 µs pulses with duty cycle ≤ 10%.
Can the MON5 pin be used simultaneously as wake-up input and LED driver?
No-MON5/HS_LED is a dual-function pin with mutually exclusive operation: configured as either a high-voltage wake-up input (bi-level sensitive, 28 V tolerant) or a 40 mA constant-current high-side LED sink. Configuration is determined at runtime via SPI register settings; both functions cannot operate concurrently.
Does the embedded MCU support in-system programming without removing the chip?
Yes-the 16 kB Flash memory supports in-system programming via the LIN interface using LIN Fast Mode, as documented in Section 18.3 of the datasheet. This enables firmware updates in vehicle without physical access to debug headers or chip removal, using only the LIN bus and host ECU.
What is the operating voltage range for the VBAT_SENSE input?
The VBAT_SENSE pin accepts a scaled-down battery voltage via external resistor divider, with input range of 0 V to 5 V. The internal ADC uses this signal to monitor raw battery voltage; typical scaling ratio is 1:10 (e.g., 12 V battery → 1.2 V at pin), enabling accurate measurement up to 40 V battery systems.
