Functional Description
The TLE 6236 G is an octal-low-side power switch which provides a serial peripheral interface
(SPI) to control the 8 power DMOS switches, as well as diagnostic feedback. The power tran-
sistors are protected against short to
V
BB
,
overload, overtemperature and against overvoltage
by an active zener clamp.
The diagnostic logic recognizes a fault condition which can be read out via the serial diagnos-
tic output (SO).
Circuit Description
Output Stage Control
Each output is independently controlled by an output latch and a common reset line, which
disables all eight outputs. Serial data input (SI) is read on the falling edge of the serial clock. A
logic high input data bit turns the respective output channel ON, a logic low data bit turns it
OFF.
CS
must be low whilst shifting all the serial data into the device. A low-to-high transition
of
CS
transfers the serial data input bits to the output buffer.
Special conditions for Channel 1 to 4:
In addition to the serial control of the outputs it is possible to control channel 1 to channel 4
directly in parallel for PWM applications. These inputs are high active and
ORed
with the SPI
control bit. The parallel inputs are provided with internal pull down sources, to guarantee that
the channels are switched off when the inputs are not connected.
The table shows the OR-operation of the parallel inputs 1 ..4 and the corresponding SPI bits.
The outputs 5 .. 8 can be controlled in serial via SPI
