SPOC - BTS6480SF
Overview
Configuration and status diagnosis are done via SPI. The SPI is daisy chain capable. The device provides a
current sense signal per channel that is multiplexed to the diagnosis pin IS. It can be enabled and disabled via SPI
commands. An over load and over temperature flag is provided in the SPI diagnosis word. A multiplexed switch
bypass monitor provides short-circuit to VBB diagnosis. In OFF state a current source can be switched to the output
of one selected channel in order to detect an open load.
Additionally, there is an integrated PWM generator implemented, which allows autonomous PWM operation with
programmable phase shifts, duty cycles and PWM frequencies. The status diagnosis and the current sense signal
is available for each channel.
The device provides an external driver capability for two external devices. For each external driver there are two
control outputs available: one output for controlling the input and one output for diagnosis enable input. The current
sense output of the external smart power drivers can be connected to the IS pin. The external drivers can be
controlled by the automatic PWM generator as well.
The SPOC - BTS6480SF provides a fail-safe feature via limp home input pin.
The power transistors are built by N-channel vertical power MOSFETs with charge pumps.

1) Not subject to production test, specified by design.
2) Device is mounted on an FR4 2s2p board according to Jedec JESD51-2,-5,-7 at natural convection; The product
(chip+package) was simulated on a 76.4 x 114.3 x 1.5 mm board with 2 inner copper layers (2 x 70 µm Cu, 2 x 35 µm Cu).
Where applicable, a thermal via array under the package contacted the first inner copper layer.
3) In accordance to AEC Q100-012 and AEC Q101-006.
4) RI is the internal resistance of the load dump pulse generator.
5) Over current protection is a protection feature. Operation in over current protection is considered as “outside” normal
operating range. Protection features are not designed for continuous repetitive operation.
6) Pulse shape represents inductive switch off: ID(t) = ID(0) × (1 - t / tpulse); 0 < t < tpulse
7) ESD resistivity, HBM according to EIA/JESD 22-A 114B (1.5 kΩ, 100 pF)
Note: Stresses above the ones listed here may cause permanent damage to the device. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
Note: Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are
not designed for continuous repetitive operation.
