Product details

Overview

TLE82094SACUMA1 from Infineon Technologies is a quad half-bridge motor driver IC designed for automotive body control modules, operating from 4.4 V to 5.25 V supply, delivering up to 600 mA per channel with integrated diagnostics, thermal shutdown, and overcurrent protection. It interfaces directly with microcontrollers via SPI and supports PWM-controlled DC motor actuation in door lock, mirror adjust, and HVAC flap applications.

For engineers reviewing the TLE82094SACUMA1 datasheet, TLE82094SACUMA1 pinout, TLE82094SACUMA1 application, or TLE82094SACUMA1 equivalent, key selection criteria include SPI-configurable current limits, integrated open-load detection per channel, fault reporting via dedicated nFAULT pin, and AEC-Q100 Grade 1 qualification for under-hood use.

Technical Context

This device implements four independent high-side/low-side configurable half-bridges controlled via 16-bit SPI interface with write-protected configuration registers. Each channel supports programmable current sense gain (10 mV/A or 20 mV/A), slew-rate control, and individual enable/disable via SPI or hardware EN pins.

Diagnostic architecture includes real-time overtemperature flag, per-channel open-load detection in high-side and low-side modes, short-to-battery/short-to-ground detection, and cyclic redundancy check (CRC) on SPI commands - all reported through a single bidirectional nFAULT pin with priority-encoded pulse-width modulated fault codes.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	4.4 V to 5.25 V - compatible with automotive 5 V rail with ±5% tolerance and brown-out immunity
Output Current per Channel	600 mA continuous - sufficient for driving small solenoids, stepper coil phases, or 12 V DC motors up to 10 W
Current Sense Accuracy	±10% at 600 mA - enables reliable closed-loop current limiting without external shunt resistors
SPI Interface Speed	Up to 5 MHz - supports fast reconfiguration during runtime, e.g., dynamic torque adjustment per actuator
Thermal Shutdown Threshold	175 °C junction - protects against sustained overload in sealed enclosures without forced airflow
AEC-Q100 Grade	Grade 1 (−40 °C to +125 °C ambient) - qualified for engine bay and passenger compartment locations

Pinout & Package

Supplied in 20-pin DSO (Dual Small Outline) package with exposed thermal pad (EP), 0.65 mm pitch, body size 7.5 mm × 4.4 mm, JEDEC MO-153 compliant. Pin 1 marked by dot; thermal pad soldered to PCB ground plane for 2.5 K/W junction-to-board thermal resistance.

Pin/Terminal	Circuit Role	Design Meaning
VBB	Power supply input	Connects to 5 V automotive rail; decoupling capacitor required within 5 mm
GND	Ground reference	Common return for power, logic, and current sense; tied to thermal pad
nCS	SPI chip select	Active-low signal enabling SPI communication; must be held high between transfers
MOSI	SPI data input	Receives 16-bit command words including address, data, and CRC bits
MISO	SPI data output	Returns status register contents and fault code pulses on nFAULT pin
SCLK	SPI clock input	Accepts up to 5 MHz clock; synchronous edge-triggered sampling
nFAULT	Fault reporting output	Open-drain output pulsing fault codes (e.g., 3× short = overtemperature)
EN1–EN4	Hardware channel enable	Optional TTL-level inputs overriding SPI control for safety-critical override
H1–H4	High-side outputs	Drain connections to load anodes; each rated for 40 V abs max
L1–L4	Low-side outputs	Source connections to load cathodes; integrated freewheeling diodes

Key Features

Feature	Design Value
Configurable half-bridge direction	Each of four channels can be set as high-side, low-side, or push-pull via SPI register - eliminates need for external H-bridge wiring
Integrated current sense	On-die sense FETs with selectable gain (10/20 mV/A) - removes external sense resistor and amplifier, saving 3 BOM items per channel
Open-load detection	Detects disconnected loads in both high-side and low-side configurations using internal test current sources - critical for fail-safe door latch monitoring
SPI CRC protection	8-bit CRC appended to every 16-bit command - prevents misconfiguration from EMI-induced bit flips on noisy vehicle harnesses
Priority-encoded fault signaling	nFAULT pin outputs distinct pulse widths for overtemperature, overcurrent, open-load, and short-circuit - enables single-wire diagnostic decoding by host MCU

Applications

Automotive Door Lock Actuation

Auto HVAC Air Flap Control

Use Scenario: Driving reversible solenoid locks in central locking systems with position feedback via current signature analysis.

IC Role / Device Role / Timing Role: Quad half-bridge provides independent forward/reverse drive per lock motor while monitoring coil current for end-of-travel detection.

Use Value: Eliminates discrete H-bridge + sense resistor + comparator per lock, reducing PCB area by 42% and enabling software-based jam detection.

Use Scenario: Controlling bi-directional DC motors that rotate HVAC blend doors in climate control units.

IC Role / Device Role / Timing Role: Four channels drive two dual-coil actuators or four single-motor flaps with synchronized PWM timing and stall detection.

Use Value: Integrated open-load detection confirms motor attachment before power-up, preventing erroneous "stuck flap" error codes during startup.

Power Seat Position Memory

Electric Parking Brake (EPB) Auxiliary Actuation

Use Scenario: Operating small DC motors for seat fore/aft and recline adjustment with soft-start and current-limited acceleration.

IC Role / Device Role / Timing Role: Configured as two push-pull bridges per motor, enabling precise bidirectional torque control via SPI-set current limits.

Use Value: Programmable slew rate prevents mechanical shock during seat movement, extending geartrain life and meeting OEM NVH targets.

Use Scenario: Driving auxiliary release solenoids or secondary brake caliper actuators in redundant EPB subsystems.

IC Role / Device Role / Timing Role: Dedicated channel delivers controlled 600 mA pulse with thermal foldback to prevent coil overheating during extended hold.

Use Value: Built-in overtemperature shutdown ensures safe deactivation if primary EPB controller fails, satisfying ASIL-B functional safety requirements.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad half-bridge motor driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN840TR	3-phase BLDC driver with integrated gate drivers; no SPI interface; analog current sense only	Targeted at fan/pump commutation, not discrete solenoid/DC motor control	Choose when driving brushless motors with hall sensors and no need for diagnostic reporting
DRV8876PWPR	Dual H-bridge, 3.3 V logic compatible, no integrated diagnostics or SPI, lower voltage rating (4.5–37 V)	Designed for industrial DC motor control where AEC-Q100 and fault reporting are not required	Prefer for cost-sensitive non-automotive applications needing higher voltage swing but no embedded diagnostics

Compared with STSPIN840TR and DRV8876PWPR, TLE82094SACUMA1 uniquely combines AEC-Q100 Grade 1 qualification, SPI-configurable diagnostics, and quad half-bridge flexibility - making it the only option for automotive body controllers requiring ISO 26262-compliant fault handling and multi-actuator consolidation.

FAQ

What is the maximum junction temperature and thermal derating behavior of TLE82094SACUMA1?

The device features thermal shutdown at 175 °C junction temperature with automatic recovery after cooldown. Derating begins above 125 °C ambient: output current reduces linearly to 300 mA at 150 °C ambient when mounted on 2-layer PCB with 200 mm² copper pour under the EP pad. Full 600 mA operation is guaranteed only up to 125 °C ambient with proper thermal layout.

Does TLE82094SACUMA1 support daisy-chained SPI configuration for multiple devices?

No, TLE82094SACUMA1 does not support daisy-chaining. Each device requires its own dedicated nCS line because the SPI interface lacks a hardware address pin or auto-addressing logic. However, up to eight devices can share MOSI/MISO/SCLK lines with individual nCS routing, minimizing MCU pin count while maintaining independent command targeting.

How is open-load detection implemented and what load impedance range does it cover?

Open-load detection uses internal 10 µA test current sources injected into each high-side and low-side output during idle periods. It reliably detects impedances above 10 kΩ for high-side and 5 kΩ for low-side configurations. Detection occurs within 100 µs and is reported in the status register; no external components are needed.

Can EN1–EN4 pins be used for functional safety monitoring independent of SPI commands?

Yes. EN1–EN4 are asynchronous hardware enables that override SPI-configured channel states. They can be driven by external safety microcontrollers or watchdog circuits to force immediate channel disable during fault conditions - providing a hardware-level safety path compliant with ASIL-B requirements without relying on SPI communication integrity.
