H-bridge Safe Operating Area (per Infineon datasheet)
Typical Applications
TLE82092SAAUMA1 is suitable for 6 applications: Electronic Throttle Body (ETC) Control, Exhaust Gas Recirculation (EGR) Valve Actuator, Variable-Geometry Turbocharger (VGT) Actuator, Electric Park Brake (EPB) Clamp Actuator, Automatic Transmission Shift Valve, HVAC Air Damper / Blend Door Actuator.
Electronic Throttle Body (ETC) Control
The TLE82092SAAUMA1 is widely deployed in drive-by-wire electronic throttle bodies where its 5.5 A continuous H-bridge current directly drives the throttle plate actuator motor. The four programmable current-limit ranges let the ECU calibration adapt inrush profiles during cold-start, while SPI diagnostics provide the open-load and short-circuit detection required for ASIL-B throttle monitoring. Operating from 5 V to 28 V (40 V transient) it tolerates load-dump on the 12 V automotive bus, and the -40 C to +150 C junction range handles under-hood thermal stress. Two programmable slew rates reduce EMI on long throttle body harnesses adjacent to AM/FM antenna paths.
Recommended
Exhaust Gas Recirculation (EGR) Valve Actuator
In EGR valve actuation the TLE82092SAAUMA1 drives the DC motor that modulates exhaust gas recirculation flow. Its SPI-programmable current limit prevents stall-current damage when the valve reaches end-of-travel, and the slew-rate control limits inrush on the actuator harness. The 5.5 A continuous rating covers most gasoline EGR actuators, while the 28 V supply tolerance handles 24 V heavy-duty truck architectures. On-die thermal shutdown and short-to-battery detection protect against the harsh exhaust-proximity thermal and electrical environment, satisfying ASIL-B functional safety targets for emissions compliance.
Recommended
Variable-Geometry Turbocharger (VGT) Actuator
The TLE82092SAAUMA1 controls VGT vane position in diesel and gasoline turbochargers, where its H-bridge topology provides bidirectional torque on the actuator motor. Programmable slew rates reduce audible PWM noise, while the SPI diagnostics flag mechanical jamming (open-load detection when the motor stalls). The 5.5 A continuous current matches typical VGT actuator draw, and the 40 V transient rating survives alternator load-dump on the 12 V rail. Infineon's SMART7 process technology supports -40 C to +150 C operation, critical for under-hood proximity to the hot turbocharger housing.
Recommended
Electric Park Brake (EPB) Clamp Actuator
The TLE82092SAAUMA1 drives the EPB DC motor that clamps the parking brake, where functional safety demands ASIL-B fault detection on every actuation. The 4 programmable current ranges let the ECU differentiate clamp, hold, and release current profiles, while the SPI diagnostic readback verifies motor connection before torque is applied. Its 5.5 A continuous current is well-matched to typical EPB actuator motors, and the 28 V supply range tolerates 24 V chassis trucks. The exposed-pad PG-DSO-20-65 package spreads heat during the high-current clamp pulse, while internal over-temperature shutdown provides a second safety layer.
Recommended
Automatic Transmission Shift Valve
The TLE82092SAAUMA1 actuates hydraulic shift valves in automatic transmissions by driving solenoid-connected DC motors, where its H-bridge polarity-reversal capability handles up- and down-shifts with one IC. SPI configurability enables per-gear current profiles, and the four current-limit thresholds prevent valve-seat damage at end-of-travel. The 5 V to 28 V supply range accommodates 12 V passenger-car and 24 V commercial-vehicle architectures, and the ASIL-B diagnostic set (open-load, short-to-ground, short-to-Vbb) supports ISO 26262 transmission controllers. The exposed-pad package sustains continuous 5 A shifts without external heatsinking.
Recommended
HVAC Air Damper / Blend Door Actuator
In automotive HVAC systems the TLE82092SAAUMA1 drives the DC motors that position blend-door, mode-door, and recirc-door dampers, where its bidirectional H-bridge output replaces a relay pair with a single SPI-controlled IC. The 5.5 A continuous current handles larger blend doors, and the programmable slew rate reduces the audible PWM whine that HVAC actuators are notorious for. Operating from 5 V to 28 V it supports both 12 V and 24 V vehicle platforms, while the 4 selectable current-limit thresholds protect the small gear motors from stall damage at end-of-travel. SPI diagnostics allow the HVAC controller to flag jammed doors before they overstress the linkage.

Design Notes
The PG-DSO-20-65 exposed-pad package requires at least 6 cm^2 of 2 oz copper on the top layer and 4 cm^2 on the bottom layer, stitched with thermal vias, to achieve the datasheet's ~36 C/W theta_JA. Without proper copper spreading, junction temperature at 5.5 A continuous and 12 V supply can exceed 150 C and trigger thermal shutdown - always size the pad per Infineon's application note before derating current. Estimated: at 5.5 A and 12 V supply, dissipation is 12 V x 5.5 A x Rds(on); with Rds(on) of ~0.1 ohm per switch (two switches in series), the H-bridge dissipates ~6 W, requiring careful thermal design.
Place the Vbb bypass capacitors (at least 100 nF ceramic + 10 uF electrolytic) within 5 mm of the Vbb pin (pin 5). Keep the high-current motor traces (OUT1, OUT2, Vbb, GND) wide (>=2 mm on outer layers, >=1 mm inner) and minimize loop area between the H-bridge and the motor terminals to reduce radiated EMI. The exposed pad (pin 20) MUST be soldered to a top-layer copper pour with at least 9 thermal vias to the inner ground plane.
Do not enable the output stages before completing the SPI initialization sequence - the device powers up with outputs disabled and requires the CONFIG register to be written first. Cross-conduction (shoot-through) is internally prevented with programmable dead-time, but if the SPI clock is missing or corrupted the outputs will not respond; verify CSN, SCLK, and SDI signal integrity with an oscilloscope before debugging the motor side. Do not exceed 28 V continuous on Vbb, even though 40 V transient is tolerated.
Route the SPI bus (CSN, SCLK, SDI, SDO) on an inner layer or shielded away from the OUT1/OUT2 motor traces; capacitive coupling from motor switching edges can corrupt SPI readback. Place a small RC filter (100 ohm + 100 pF) on the SDO line if long harness lengths are unavoidable. Keep the VCC logic supply decoupling (100 nF ceramic) within 3 mm of the VCC pin, and provide a ferr bead or resistor between Vbb and VCC if the host MCU shares the same 5 V rail.
