4 / 59 page  TLE 6368 / SONIC Data Sheet 4 Rev. 2.2, 2006-12-01 1.4 Pin definitions and functions Pin No. Symbol Function 1,18,19, 36 GND Ground; to reduce thermal resistance place cooling areas on PCB close to these pins. The GND pins are connected internally to the heat slug at the bottom. 2CLK SPI Interface Clock input; clocks the shift register; CLK has an internal active pull down and requires CMOS logic level inputs;see also chapter SPI 3CS SPI Interface chip select input; CS is an active low input; serial communication is enabled by pulling the CS terminal low; CS input should only be switched when CLK is low; CS has an internal active pull up and requires CMOS logic level inputs ;see also chapter SPI 4DI SPI Interface Data input; receives serial data from the control device; serial data transmitted to DI is a 16 bit control word with the Least Significant Bit (LSB) being transferred first; the input has an active pull down and requires CMOS logic level inputs; DI will accept data on the falling edge of CLK-signal; see also chapter SPI 5DO SPI Interface Data output; this tristate output transfers diagnosis data to the controlling device; the output will remain 3- stated unless the device is selected by a low on Chip-Select CS; see also the chapter SPI 6ERR Error output; push-pull output. Monitors failures in parallel to the SPI diagnosis word, reset via SPI. ERR is an active low, latched output. 7Q_STB Standby Regulator Output; the output is active even when the buck regulator and all other circuitry is in off mode 8 Q_T1 Voltage Tracker Output T1 tracked to Q_LDO1; bypass with a 1µF ceramic capacitor for stability. It is switched on and off by SPI command. Keep open, if not needed. 9 Q_T2 Voltage Tracker Output T2 tracked to Q_LDO1; bypass with a 1µF ceramic capacitor for stability. It is switched on and off by SPI command. Keep open, if not needed. 10 Q_T3 Voltage Tracker Output T3 tracked to Q_LDO1; bypass with a 1µF ceramic capacitor for stability. It is switched on and off by SPI command. Keep open, if not needed. |
