SPOC™+2 | Multichannel SPI High-Side Power Controller
For resistive, inductive, capacitive and high inrush current loads – to replace relays, fuses and discrete circuits.
SPOC™ +2 is the latest generation of software configurable multichannel serial interface power controllers for automotive and industrial applications based on SMART7 technology. Control, configuration and diagnostics of the SPOC™ +2 devices are carried out via Serial Peripheral Interface (SPI). The family offers 4- and 6- channel devices (from 5.5 mΩ to 70 mΩ) in a TSDSO-24 exposed pad package and provides state of the art diagnostics and protection features.
Body control modules (BCM) and power distribution centers (zone control units, power distribution units, relay and fuse boxes) become increasingly complex, therefore the partition and software flexibility of SPOC™ +2 with a number of advanced features is the right solution.
A very low ohmic DMOS power stage combined with protection and diagnostic features make the SPOC™ +2 family suitable for resistive, inductive, capacitive and high inrush current loads and can replace relays, fuses and discrete circuits. The product family is designed to address applications such as power distribution to ECUs, exterior and interior lighting with lamps and LEDs, sensor supply and heating.
The product family offers unique software configurable protection features, which can be applied individually for each channel. Besides state-of-the-art functions like short-circuit, overcurrent protection and temperature protection, SPOC™ +2 includes a configurable overcurrent detection threshold. The protection can either be configured with intelligent restart control or with intelligent latch. Furthermore, also the kILIS factor (ratio between load current and sense current) and the switching slew rate can be configured in order to address different applications. For all SPOC™ +2 products Infineon provides a common SPI concept to allow full software re-use. The devices include enhanced diagnosis functions such as open load and short circuit to battery detection.
A unique benefit of the SPOC™ +2 family is the pin-compatibility within the 4- and 6- channel devices. Based on the identical footprint of its packages, maximum design flexibility is provided, allowing an easy adaption to the load without major modification of the PCB layout.
PWM operation over SPI, compliance with the most severe reverse battery requirements (through reverse ON feature), reduced operating current consumption, simplified and cost-efficient ground network with integrated diode, outstanding current sense accuracy, benchmark cranking voltage specification (down to 3.1 V) and SPI daisy-chain capability are the key factors for the success of SPOC™ +2 in the automotive market. Furthermore, the concept allows a channel parallelization where two channels drive one load. Consequently, the supported currents are in the range of 1.5 A to 14 A.

SPOC™+2 is the new generation of multichannel high-side power controllers for automotive and industrial applications based on SMART7 technology. Control, configuration and diagnostics are carried out via Serial Peripheral Interface (SPI).
SPOC™+2 is designed to address additional applications such as door lock, seat heating, interior lighting as well as lighting and power distribution loads e.g. for e-bikes. Thanks to its flexibility and new features, SPOC™+2 is the right solution to complex modules e.g. BCMs, junction and relay boxes.
The newest smart switches family SPOC™+2 inherited the sustained technological know-how of the previous families to achieve excellence.
In addition to their different features, you can be sure, when opting for SPOC™+2, that you will:
- Significant PCB are saving, due to their smaller packages (PG-TSDSO-24)
- Cost saving, thanks to the integrated GND diode and the smaller package
- Scalability of family devices (pin-to-pin compatibility)
- Very low power dissipation, thanks to the SMART7 technology that enables very low RDS(ON)
- Improved register structure for more flexibility
- New registers for increased load driving capability
- Alternating SPI response to reduce firmware complexity
Infineon offers various support materials:
- Data Sheets
- Evaluation boards (Motherboard and daughterboard)
- Config Wizard for IPD (Configuration and evaluation tool)
- Videos
- Simulations models
