Product details

Overview

TLE82092SAAUMA1 from Infineon Technologies is a SPI-programmable dual half-bridge H-bridge IC for automotive DC motor control, featuring 240 mΩ typical full-path R_DS(on), 1.5–8.6 A programmable current limit, 4.5–28 V battery supply range, and AEC-Q100 qualification. It operates as an H-bridge or two independent half-bridges in safety-critical systems such as power seat actuators and HVAC blower control.

For engineers reviewing the TLE82092SAAUMA1 datasheet, TLE82092SAAUMA1 pinout, TLE82092SAAUMA1 application, or TLE82092SAAUMA1 equivalent, key selection considerations include SPI-configurable slew rate, temperature-dependent current reduction above 165°C, open-load detection in off-state, VS undervoltage shutdown, and dual-mode (SPI/status flag) diagnostic interface compatibility.

Technical Context

The device integrates two N-channel high-side and two N-channel low-side power stages with integrated gate drivers, charge pump (CP pin), and internal VDD monitoring circuitry that forces safe shutdown on VDD over/undervoltage. Its logic inputs (IN1/IN2, DIS, ABE) support parallel control while SPI (SI/SO/SCK/SS) enables real-time configuration of current limit, slew rate, and fault reporting.

Protection architecture includes short-circuit-to-ground/battery detection, overtemperature shutdown with thermal warning bit, open-load diagnosis in off-state, and junction temperature-dependent current derating starting at 165°C. All I/O pins tolerate up to 18 V, and standby current is 8 µA typical.

Pinout & Package

Package: PG-DSO-20-65 (20-pin exposed-pad SOIC with 430 mil body width; heatslug connected to pin 21 and requires PCB thermal pad connection).

Pin/Terminal	Circuit Role	Design Meaning
1, 10, 11, 20, 21	GND / Heatslug	Power ground return path and thermal interface; pin 21 is exposed thermal pad requiring soldered PCB copper area.
2	SO (SPI Serial Out)	Active-low SPI data output during read operations; must be tied to GND in status flag mode.
3	VDDIO	Digital output buffer supply; sets logic level for SO and SF; connects to GND to enable status flag mode.
4	SS/SF	Slave Select (SPI mode) or Status Flag (low-active fault indicator); dual-function pin selected by VDDIO state.
5	CP	Charge pump capacitor node; external 100 nF ceramic capacitor required for high-side gate drive voltage generation.
6, 15	VS	Main battery input (4.5–28 V); pins 6 and 15 must be shorted externally to handle high-current paths and reduce trace inductance.
7, 14	IN1, IN2	Parallel logic inputs for half-bridge control; TTL/CMOS-compatible with 18 V overvoltage tolerance.
8, 13	OUT1, OUT2	High-current power outputs (up to 8.6 A); each drives one side of H-bridge or independent load; ESD rated ±8 kV HBM.
9	DIS	Global disable input; asynchronous active-low signal forcing both half-bridges into high-impedance state.
12	ABE	Bidirectional enable; controls direction of current flow in H-bridge mode and enables diagnostics in status flag mode.
16	SI	SPI Serial Input; receives configuration and command data; tied to GND in status flag mode.
17	SCK	SPI clock input; synchronous edge-triggered; max 1 MHz clock rate per datasheet section 9.1.
18	VDD	Digital core supply (4.4–5.25 V); monitored for over/undervoltage shutdown to prevent unsafe logic operation.
19	GNDABE	Separate sense ground for VDD monitoring; improves accuracy of supply voltage detection under noisy conditions.

Key Features

Feature	Design Value
Configurable as H-bridge or dual half-bridge	Single IC supports bidirectional motor control (H-bridge) or independent solenoid/unidirectional motor drive (two half-bridges), reducing BOM count.
Slew rate programmability via SPI	Two settings (fast/slow) reduce EMI during switching transitions and mitigate voltage spikes on inductive loads.
Open-load diagnosis in off-state	Detects disconnected loads before activation, preventing false fault triggers and enabling pre-drive system validation.
Temperature-dependent current reduction	Linear derating of current limit above 165°C junction temperature prevents thermal runaway during sustained overload.
Status Flag mode (no SPI required)	Single-pin (SS/SF) active-low fault indication supports basic diagnostics in cost-sensitive or space-constrained designs.

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BTS7200-2EPA	Non-SPI, fixed current limit (5.5 A typ.), no slew rate control, single status flag only.	Lacks programmability and advanced diagnostics; suited for simpler, lower-cost seat/mirror modules.	Select when SPI configuration and fine-grained current tuning are unnecessary and BOM cost is critical.
VNH7040ASTR	Higher R_DS(on) (350 mΩ), no temperature-dependent current reduction, no CP pin (integrated charge pump).	Lower integration density; requires larger PCB area due to higher thermal resistance (R_thJA = 25 K/W vs. 17 K/W).	Prefer when existing layout uses ST's footprint and diagnostics via SPI are not required.

Compared with BTS7200-2EPA and VNH7040ASTR, TLE82092SAAUMA1 offers superior thermal performance, SPI-based real-time current/slew tuning, and junction-temperature-aware protection-critical for ASIL-B–aligned systems where dynamic fault mitigation is mandatory.

FAQ

What is the maximum continuous output current supported by TLE82092SAAUMA1?

The device supports up to 8.6 A typical continuous output current per channel when configured as a half-bridge, based on its 240 mΩ full-path R_DS(on) and thermal design with R_thJA = 17 K/W on a 2s2p FR4 board. Actual current capability depends on PCB copper area, ambient temperature, and airflow; derating begins linearly above 165°C junction temperature.

How does the status flag (SF) mode differ from SPI mode in operation?

Status flag mode activates when VDDIO is tied to GND, repurposing SS/SF as a single active-low fault indicator reflecting combined overtemperature, short-circuit, or undervoltage events. SPI mode requires VDDIO at 4.4–5.25 V and uses SS/SF as chip-select, enabling granular fault register reads, current limit reconfiguration, and slew rate updates via SI/SO/SCK.

Is external charge pump capacitance required, and what value is specified?

Yes, an external 100 nF X7R ceramic capacitor must be placed between CP (pin 5) and GND to generate the boosted gate drive voltage for high-side N-channel MOSFETs. This capacitor must be located within 5 mm of the IC with low-inductance routing to ensure stable charge pump operation and prevent shoot-through during switching transitions.

Does TLE82092SAAUMA1 support PWM control, and what is the maximum frequency?

Yes, it supports PWM control of connected DC motors with a maximum switching frequency of 11 kHz, as specified in Section 4.2.4 of the datasheet. This frequency avoids audible noise in most automotive cabin applications while maintaining efficient power delivery and manageable switching losses in the 240 mΩ power stage.
