Functional Description
The TLE 6230 GP is an octal-low-side power switch which provides a serial peripheral inter-
face (SPI) to control the 8 power DMOS switches, as well as diagnostic feedback. The power
transistors are protected against short to V
voltage by an active zener clamp.
The diagnostic logic recognizes a fault condition which can be read out via the serial diagnostic
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 or low active (programmable
via PRG pin) and ANDed with the SPI control bit.
The table shows the AND-operation of the parallel
input pin (here active high) and the corresponding
SPI bit. For an application where the parallel input is
always "ON", it is possible to switch the channel
OFF via the SPI bit, e.g. for diagnosis in OFF-state.
⇒ SPI Priority for OFF-state
Operation with parallel inputs: Set SPI bits to logic high.
Operation via SPI: Connect parallel inputs to logic high (if programmed to active high).
PRG - Program pin.
If the parallel input pins are not connected (independent of high or low activity) it is guaranteed
that the channels 1 to 4 are switched OFF.
PRG pin itself is internally pulled up when it is not connected.
