Product details

Overview

TLE7209-2R from Infineon Technologies is an intelligent full H-bridge IC for bidirectional DC motor control in safety-critical automotive and industrial systems, featuring 5–28 V operating supply, 150 mΩ typical R_DS(on) per channel at 25 °C, 5 A continuous DC load current (T_C < 100 °C), integrated chopper current limitation (6.6 A ± 1.1 A), and dual diagnostic modes (SPI or status flag).

For engineers reviewing the TLE7209-2R datasheet, TLE7209-2R pinout, TLE7209-2R application, or TLE7209-2R equivalent, key selection considerations include its P-DSO-20-12 package with metal slug grounded internally, configurable DMS pin for SPI/status-flag diagnostics, tristate-safe fault response, and integrated charge pump enabling high-side n-channel DMOS drive without external bootstrap components.

Technical Context

The TLE7209-2R implements a fully protected H-bridge using four n-channel DMOS power transistors with integrated freewheeling diodes and an internal charge pump for high-side gate drive. It supports direct parallel input control (IN1/IN2) and enable/disable logic (EN/DIS), with all outputs forced to tristate during overtemperature, short circuit, or undervoltage faults.

Diagnostic capability is selectable via DMS pin voltage: grounding enables single-pin status-flag reporting (SCK/SF), while applying V_CC activates 8-bit SPI interface (SDI/SDO/SCK/SF/CSN) for detailed register-based fault logging including SCG1/SCG2, SCB1/SCB2, SCOL, OT, and UVVS bits.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	5 V to 28 V - supports wide automotive battery range including cold-crank and load-dump conditions.
R_DS(on) (per channel)	150 mΩ typ. at 25 °C - enables low conduction loss and thermal efficiency at 5 A continuous load.
Continuous Load Current	5 A (T_C < 100 °C) - defines maximum steady-state motor current with adequate heatsinking.
Chopper Current Limit	6.6 A ± 1.1 A - active current regulation with blanking time (t_b) and off-time (t_a) prevents thermal runaway.
Switching Frequency	Up to 30 kHz - allows PWM motor speed control with minimal audible noise and EMI.
Fault Response	Tristate output on all faults - eliminates unintended motor motion during overtemperature, short circuit, or undervoltage events.
Diagnostic Interface	SPI or status flag (DMS-selectable) - provides either simple system-level error signaling or full register readout of fault sources.

Pinout & Package

P-DSO-20-12 package with exposed metal slug internally connected to GND pins; thermally optimized for PCB copper pour mounting and high-power dissipation in motor drive applications.

Pin/Terminal	Circuit Role	Design Meaning
1, 10, 11, 20	GND	Power and signal ground reference; multiple pins reduce impedance and improve thermal conduction to PCB.
2	SCK/SF	Shared pin for SPI clock (SCK) or status flag output (SF); mode selected by DMS voltage.
3, 19	IN1 / IN2	Direct logic inputs controlling OUT1/OUT2 polarity; internal pull-up enables default high state when floating.
4	VSCP	Charge pump supply input - powers internal high-side gate driver; requires local 100 nF decoupling.
5, 16	VS	Main power supply input (5–28 V); dual pins reduce IR drop and improve current sharing.
6, 7, 14, 15	OUT1 / OUT2	H-bridge output terminals; paralleled pins per side support 5 A continuous current with low inductance.
8	SDO	SPI serial data output - delivers 8-bit status register contents during SPI read cycles.
9	SDI	SPI serial data input - accepts configuration or command writes to internal control registers.
12	DMS	Diagnostic Mode Selection - GND = status flag mode; V_CC = SPI mode.
13	EN	Enable input with internal pull-down - must be driven high to activate bridge; ensures safe power-on default.
17	CSN	SPI chip select (active low) - enables SPI communication only when asserted.
18	DIS	Disable input with internal pull-up - drives outputs to tristate when high; overrides IN1/IN2 states.

Key Features

Feature	Design Value
Integrated Charge Pump	Generates gate voltage > V_S for high-side n-channel DMOS - eliminates need for external bootstrap circuitry and improves reliability.
Configurable Diagnostics	DMS pin selects between single-pin status flag or full SPI register access - balances simplicity vs. debug depth per system requirement.
Temperature-Dependent Current Limit	Reduces current limit from 6.6 A to 2.5 A as junction temperature rises from T_ILR to T_SD - prevents thermal runaway under sustained overload.
Short-Circuit Discrimination Logic	Distinguishes short-to-ground (SCG), short-to-battery (SCB), and short-across-load (SCOL) using timing windows and dual-sense detection - enables precise fault isolation.
Undervoltage Lockout (UVLO)	Disables outputs when VS falls below threshold - avoids erratic switching and MOSFET shoot-through during brownout conditions.

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
DRV8876-Q1	Lower R_DS(on) (80 mΩ), integrated current sense amplifier, no SPI interface - uses analog current monitor output.	Requires external ADC for current feedback; lacks register-based fault classification.	Preferred where analog current monitoring suffices and SPI complexity is undesirable.
VNH7040AS	Higher continuous current (7 A), same P-DSO-20 package, but only status-flag diagnostics - no SPI mode or DMS configurability.	Limited to basic fault indication; no access to individual SCG/SCB/SCOL bits.	Selected when cost-sensitive designs require robust protection without advanced diagnostics.

Compared with DRV8876-Q1 and VNH7040AS, the TLE7209-2R uniquely combines SPI-configurable diagnostics, temperature-dependent current derating, and integrated charge pump in a single P-DSO-20-12 package - making it optimal for ASIL-B systems requiring traceable fault root-cause analysis and thermal resilience.

FAQ

What is the purpose of the VSCP pin?

The VSCP pin supplies the internal charge pump that generates the boosted gate voltage required to fully enhance the high-side n-channel DMOS transistors. It must be decoupled with a 100 nF capacitor to ground and is not intended for external power routing. Operating outside its specified voltage range risks incomplete high-side turn-on and increased R_DS(on), leading to thermal stress.

How does the chopper current limitation differ from short-circuit shutdown?

The chopper current limitation (6.6 A ± 1.1 A) is a regulated, repetitive on/off cycle used for sustained overload protection, with blanking time t_b and off-time t_a. Short-circuit shutdown triggers within ~2 µs when current exceeds IOUK, forcing immediate tristate and setting dedicated SCG/SCB/SCOL flags - it responds to catastrophic faults, not gradual overloads.

Can the TLE7209-2R drive stepper motors?

Yes - the TLE7209-2R supports bipolar stepper motor control by independently driving two phases via its dual H-bridge outputs (OUT1/OUT2). Its 30 kHz switching frequency, fast rise/fall times, and integrated freewheeling diodes enable microstepping-compatible PWM operation, though external phase sequencing logic or MCU control is required.

What happens when both EN and DIS are asserted simultaneously?

When EN is low (disabled) and DIS is high (disabled), the outputs enter tristate regardless of IN1/IN2 states - DIS has priority over EN in the truth table. This hard-disable behavior ensures fail-safe motor stoppage during conflicting control signals, consistent with ASIL-B safety goals.
