Data Sheet TLE 6220 GP Functional Description The TLE 6220 GP is an quad-low-side power switch which provides a serial peripheral interface (SPI) to control the 4 power DMOS switches, as well as diagnostic feedback. The power transistors are protected against short to VBB, overload, overtemperature and against overvoltage by an active zener clamp. The diagnostic logic recognises a fault condition which can be read out via the serial diagnostic output (SO).
Data Sheet TLE 6220 GP SCLK - Serial Clock. The system clock pin clocks the internal shift register of the TLE 6220 GP. The serial input (SI) accepts data into the input shift register on the falling edge of SCLK while the serial output (SO) shifts diagnostic information out of the shift register on the rising edge of serial clock. It is essential that the SCLK pin is in a logic low state whenever chip select CS makes any transition. SI - Serial Input.
Data Sheet TLE 6220 GP Serial Control of the Outputs: SPI protocol Each output is independently controlled by an output latch and a common reset line, which disables all four outputs. The Serial 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.

Data Sheet TLE 6220 GP The OR-function is the default Boolean operation if the device restarts after a Reset, or when the supply voltage is switched on for the first time. If the OR operation is programmed it is latched until it is overwritten by the AND operation. 5.

Data Sheet TLE 6220 GP Diagnostics FAULT - Fault pin. There is a general fault pin (open drain) which shows a high to low transi- tion as soon as an error occurs for any one of the four channels. This fault indication can be used to generate a µC interrupt. Therefore a ‘diagnosis’ interrupt routine need only be called after this fault indication. This saves processor time compared to a cyclic reading of the SO information.
