Product details

Overview

BTS722204ESEXUMA1 from Infineon is a quad-channel automotive-grade high-side power switch with integrated diagnosis, protection, and SPI daisy-chain capability. It delivers 7 A (channels 0/3) and 4 A (channels 1/2) nominal load current at 85 °C, features dual R_DS(ON) values (9 mΩ / 22 mΩ), and supports 3.3 V/5 V logic for driving resistive, inductive, and capacitive loads such as 65 W and 42 W LED modules in body control modules.

For engineers reviewing the BTS722204ESEXUMA1 datasheet, BTS722204ESEXUMA1 pinout, BTS722204ESEXUMA1 application, or BTS722204ESEXUMA1 equivalent, key selection criteria include channel-specific R_DS(ON), programmable overcurrent restart, proportional current sense (k_ILIS = 5500/2500), reverse polarity handling (ReverseON), and ISO 16750-2 compliant 35 V load dump clamping.

Technical Context

This device implements four independent SMART7 high-side switches with integrated gate drivers, thermal shutdown with controlled restart, and dynamic overcurrent detection per channel. Each channel includes dedicated INn input, OUTn output, and internal current-sense multiplexing routed to a single IS pin.

The SPI interface operates up to 5 MHz with CSN, SCLK, SI, and SO signals, enabling daisy-chained configuration and real-time diagnostics including open-load (ON/OFF), short-to-battery/ground, and checksum-verified register access - all supporting ASIL-B functional safety requirements per AEC-Q100 Grade 1 qualification.

Key Specifications

Parameter	Value and Actual Design Meaning
Operating Voltage Range	4.1 V to 28 V - supports cold-crank (3.1 V UVLO) and ISO 16750-2 load dump (35 V clamp)
Channel Current Rating	7 A (CH0/CH3), 4 A (CH1/CH2) at T_A = 85 °C - enables mixed-load driving in single-package BCU designs
R_DS(ON) (T_J = 150 °C)	9 mΩ (CH0/CH3), 22 mΩ (CH1/CH2) - defines conduction loss and thermal derating margin
Current Sense Ratio	5500 (CH0/CH3), 2500 (CH1/CH2) - enables accurate load monitoring via external ADC without scaling hardware
SPI Clock Frequency	Up to 5 MHz - allows fast configuration and diagnostic polling in time-critical vehicle networks
Functional Safety	AEC-Q100 Grade 1 qualified with Limp Home mode, input status monitoring, and register checksum verification
Logic Compatibility	3.3 V and 5 V tolerant inputs - simplifies interface with diverse MCU I/O domains

Pinout & Package

Package: PG-TSDSO-24 (exposed pad, RoHS-compliant, thermally enhanced).

Pin/Terminal	Circuit Role	Design Meaning
VS	Battery supply input	Primary power rail connection; supports up to 28 V continuous, 35 V clamped transients
GND	Power ground reference	Common return path for load current and internal circuitry; tied to exposed pad
VDD	Digital supply input	3.3 V or 5 V logic domain supply; powers SPI interface and control logic
SO/SI/SCLK/CSN	SPI serial interface	Full-duplex daisy-chain capable interface; CSN active-low with internal pull-up
IN0–IN1	Channel enable inputs	High-active digital control signals; unused pins require 10 kΩ pull-down to GND
LHI	Limp Home activation	Forced safe-state override during fault conditions; high-active, failsafe activation
EDD/EDO	External driver control	Enable signals for companion smart power switches; synchronized with internal channel state
IS	Proportional current sense	Multiplexed analog output; scaled current representation for all four channels
OUT0–OUT3	Protected high-side outputs	Internally paralleled pins per channel; PCB traces must handle full channel current (7 A/4 A)

Key Features

Feature	Design Value
Dual R_DS(ON) architecture	Optimizes thermal distribution across four channels: lower-loss paths for high-current loads (CH0/CH3), higher-R paths for auxiliary functions (CH1/CH2)
InverseON operation	Enables channel turn-on under reverse battery conditions - critical for fail-safe behavior during polarity faults
ReverseON mode	Reduces quiescent dissipation during reverse polarity events by disabling internal charge pump while maintaining diagnostics
Programmable overcurrent restart	Configurable retry delay (t_RETRY = 50 ms) and trip threshold per channel - avoids nuisance tripping on motor inrush
Integrated external driver control	EDO/EDD signals coordinate timing and fault response with external PROFET™ or similar smart switches - enables scalable multi-output systems

Applications

Rear Lamp & Signaling

Engine Bay Auxiliary Loads

Use Scenario: Managing brake lights, turn signals, and fog lamps with thermal-aware duty cycling.

IC Role / Device Role / Timing Role: Fault-tolerant high-side controller with open-load detection in OFF state and short-to-ground protection during PWM modulation.

Use Value: Eliminates need for separate bulb-out detection circuits; Limp Home mode maintains partial functionality after single-channel failure.

Use Scenario: Powering engine cooling fans, fuel pumps, and HVAC actuators in harsh under-hood environments.

IC Role / Device Role / Timing Role: AEC-Q100 Grade 1 qualified power switch with dynamic overtemperature restart and reverse polarity resilience.

Use Value: Withstands -40 °C to +150 °C junction temperature; ReverseON ensures fan operation even during battery reversal during jump-start.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BTS724G	Single-channel, 60 mΩ R_DS(ON), no SPI interface, analog current sense only	Lacks daisy-chain diagnostics and multi-channel integration; requires four ICs for equivalent function	Choose when system-level diagnostics are handled externally and board space is not constrained.
BTS723GW	Quad-channel, 10 mΩ/25 mΩ R_DS(ON), SPI interface, but no EDD/EDO or InverseON support	Missing external driver coordination and reverse-polarity turn-on capability	Prefer when external smart switch coordination is unnecessary and cost optimization is primary.

Compared with BTS724G and BTS723GW, BTS722204ESEXUMA1 uniquely integrates daisy-chain SPI, InverseON, ReverseON, and dual-R_DS(ON) architecture - delivering superior system-level fault resilience and reduced component count in next-generation BCMs.

FAQ

What is the maximum allowable load dump voltage for BTS722204ESEXUMA1?

The device clamps load dump transients up to 35 V at T_J ≥ 25 °C, complying with ISO 16750-2 (2010) using a 2 Ω source impedance. This rating is validated under suppressed load dump conditions and does not require external TVS diodes for standard automotive battery systems.

How does the proportional current sense (IS pin) work across four channels?

The IS pin outputs a multiplexed analog signal representing load current from each channel sequentially, scaled by channel-specific k_ILIS ratios (5500 for CH0/CH3, 2500 for CH1/CH2). External ADC sampling must be synchronized with SPI register reads to correlate IS voltage with active channel state.

Can BTS722204ESEXUMA1 drive inductive loads like motors without external flyback protection?

Yes - the device integrates internal overvoltage clamping and energy-dissipating circuitry that safely handles inductive kickback from loads such as window lift motors or cooling fans, eliminating the need for external freewheeling diodes in most automotive applications.

What is the purpose of the EDD and EDO pins?

EDD (External Driver Diagnosis) and EDO (External Driver Output) enable coordinated control of an external smart power switch. EDO activates the external device's output synchronously with internal channel state, while EDD enables its diagnostic reporting - allowing unified fault handling across hybrid power stages.
