Product details

Overview

BTS712204ESAXUMA1 from Infineon is a 4-channel automotive-grade high-side power switch with integrated diagnosis, protection, and SPI daisy-chain interface. It delivers dual R_DS(ON) ratings (16.5 mΩ for channels 0/3, 38 mΩ for channels 1/2), supports 5 A/3 A nominal loads at 85 °C, and handles high inrush currents from 55 W and 27 W bulbs or LED modules. Used in body control modules for load driving and fault monitoring.

For engineers reviewing the BTS712204ESAXUMA1 datasheet, BTS712204ESAXUMA1 pinout, BTS712204ESAXUMA1 application, or BTS712204ESAXUMA1 equivalent, key selection criteria include channel-specific R_DS(ON), programmable overcurrent restart, proportional current sense (5000/2000 ratio), 5 MHz SPI clock support, and AEC-Q100 Grade 1 qualification for under-hood deployment.

Technical Context

The device implements four independent high-side switches with per-channel input control (IN0–IN3), Limp Home activation (LHI), and multiplexed analog current sense (IS). Protection includes dynamic temperature limiting with controlled restart, undervoltage shutdown below 3.1 V (cranking), and overvoltage clamping at ≥35 V with external components.

Diagnosis covers open-load detection in ON/OFF states, short-to-ground/battery, and SPI-reported fault flags. Functional safety features include checksum-verified configuration registers, input pin status monitoring, and current sense verification mode-enabling ASIL-B capable system integration without external safety MCU.

Key Specifications

Parameter	Value and Actual Design Meaning
Operating Voltage Range	4.1 V to 28 V - Ensures reliable operation during cold-crank (≥3.1 V UV threshold) and load-dump transients (up to 35 V with external clamp).
Channel R_DS(ON) (T_J = 150 °C)	16.5 mΩ (ch0/ch3), 38 mΩ (ch1/ch2) - Enables 5 A continuous (ch0/ch3) and 3 A continuous (ch1/ch2) drive at 85 °C ambient.
Current Sense Ratio	5000 (ch0/ch3), 2000 (ch1/ch2) - Delivers precise proportional analog output for real-time load current monitoring and diagnostics.
SPI Interface Speed	Up to 5 MHz - Supports fast configuration updates and diagnostic readback in time-critical automotive control loops.
Quiescent Current (Sleep)	≤0.7 µA at T_J ≤ 85 °C - Meets ultra-low-power requirements for always-on vehicle domains (e.g., door modules, lighting controllers).
AEC-Q100 Qualification	Grade 1 (−40 °C to +125 °C ambient) - Validated for engine bay and chassis-mounted applications with full thermal derating.

Pinout & Package

Package: PG-TSDSO-24 (exposed pad, thermally enhanced SOIC variant with 24 leads and bottom-side thermal pad).

Pin/Terminal	Circuit Role	Design Meaning
VS	Battery supply input	High-side power rail connection; supports up to 28 V continuous, 35 V transient (with external clamp).
VDD	Digital logic supply	3.3 V or 5 V tolerant I/O domain; powers SPI interface and internal logic.
GND	Ground reference	Common return for digital and power grounds; exposed pad must be soldered for thermal performance.
IN0–IN3	Channel enable inputs	"High"-active digital control signals; each independently enables its respective high-side output.
OUT0–OUT3	Protected high-side outputs	Four switched power outputs; all pins per channel internally paralleled-PCB traces must carry full channel current.
SO/SI/SCLK/CSN	SPI interface	Full-duplex serial interface with "low"-active chip select; supports daisy-chaining multiple SPOC™+2 devices.
LHI	Limp Home activation	"High"-active safety input forcing all channels into safe state on critical fault or MCU failure.
IS	Analog current sense output	Multiplexed proportional voltage output (k_ILIS = 5000/2000); requires external ADC for load current measurement.

Key Features

Feature	Design Value
Dual R_DS(ON) channel grouping	Optimizes thermal distribution: lower-resistance channels (0/3) for high-current loads (e.g., headlamps), higher-resistance (1/2) for medium-current (e.g., interior lighting).
Programmable overcurrent restart	Configurable retry delay and trip threshold per channel via SPI-enables adaptive response to inrush vs. sustained overload.
InverseON and ReverseON modes	Allows safe switching during reverse polarity or inverse current conditions-reduces power dissipation and prevents latch-up in battery-reversal scenarios.
Integrated open-load and short-circuit diagnosis	Detects open-circuit (OFF/ON), short-to-ground, and short-to-battery faults on all channels-eliminates need for external sensing circuitry.

Applications

Rear Lighting Control

Use Scenario: Driving 55 W halogen or equivalent LED headlamp modules in adaptive front-lighting systems.

IC Role / Device Role / Timing Role: High-side power switch with real-time current monitoring and open-load detection for lamp integrity verification.

Use Value: Enables automatic bulb-out reporting and thermal derating based on measured load current-replacing discrete relays and fuses.

Use Scenario: Controlling 27 W rear combination lamps (brake/tail/turn) in modular rear lighting clusters.

IC Role / Device Role / Timing Role: Four-channel protected driver with daisy-chained SPI for centralized BCU control and fault logging.

Use Value: Reduces wiring harness complexity and ECU pin count while supporting PWM dimming via INx pulse-width modulation.

Door Module Power Distribution

Seat Control Unit Loads

Use Scenario: Powering window lift motors, mirror heaters, and interior courtesy lights from a single door ECU.

IC Role / Device Role / Timing Role: High-side load switch with Limp Home mode activated on CAN bus timeout or MCU reset.

Use Value: Maintains safe default state (e.g., windows stopped, heaters off) during communication loss-meeting ISO 26262 ASIL-B requirements.

Use Scenario: Driving seat heater elements, lumbar adjust actuators, and position sensor bias supplies.

IC Role / Device Role / Timing Role: Protected power controller with proportional current sense for heater temperature estimation and overtemperature cut-off.

Use Value: Eliminates separate current-sense resistors and op-amps-reducing BOM cost and PCB area by >30% versus discrete solutions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side power switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BTS716204ESAXUMA1	Same SPOC™+2 family; 6-channel version with identical R_DS(ON) specs and SPI interface.	Higher channel count suits multi-load zones (e.g., full-body control module) but requires larger PCB footprint.	Select when consolidating >4 loads onto one IC to reduce component count and interconnect complexity.
TPS4H160-Q1	TI 4-channel high-side switch; 12 mΩ typical R_DS(ON), no integrated current sense, uses parallel GPIO control instead of SPI.	Lacks multiplexed analog current sense and daisy-chain capability-requires more MCU pins and external sensing for diagnostics.	Choose for simpler, non-networked systems where SPI overhead is undesirable and current monitoring is handled externally.

Compared with BTS712204ESAXUMA1, the BTS716204ESAXUMA1 offers scalability for higher channel density without sacrificing diagnostic depth, while the TPS4H160-Q1 trades integrated intelligence for lower gate count and deterministic GPIO timing-making it suitable for cost-sensitive, non-SPI architectures.

FAQ

What is the maximum allowable voltage on the VS pin during load dump?

The BTS712204ESAXUMA1 withstands up to 35 V on the VS pin during load dump events per ISO 16750-2 (2010) with 2 Ω source impedance. This rating assumes proper external overvoltage clamping circuitry (e.g., TVS diode) is implemented per Infineon's recommended layout in Chapter 11.2 of the datasheet.

How does the Limp Home mode function during MCU failure?

Limp Home mode activates when the LHI pin is driven high, forcing all four channels into a defined safe state-either OFF or configured via SPI register settings before fault occurrence. It operates independently of SPI communication, ensuring fail-safe behavior even if the microcontroller freezes or loses power, meeting ASIL-B fault containment requirements.

Can the IS pin provide simultaneous current readings for all four channels?

No-the IS pin delivers a time-multiplexed analog voltage representing the load current of only one selected channel at a time. Channel selection is controlled via SPI configuration register (CHSEL bits). To monitor all four channels, sequential SPI writes and ADC sampling are required, with minimum 10 µs settling time between channel switches.

Is the exposed thermal pad electrically isolated?

No-the exposed pad (EP) is internally connected to the VS potential and must be soldered to a large copper pour tied to the battery rail for optimal thermal performance and EMI suppression. Electrical isolation is not supported; using insulating thermal interface materials would compromise both thermal resistance and electrical integrity.
