Pin Symbol Function

1 / TAB GND

Ground

Reference potential

6IN/PWM

IN/PWM direct mode:

Direct input for channel 2. Other channels can be driven in PWM mode via SPI.

8VCC

Logic voltage supply 3.3 V/5 V:

For this input a ceramic capacitor as close as possible to GND is recommended

3 SRC1 Source of configurable channel 1

4 DRN1 Drain of self configurable channel 1, in HS mode also V

supply

5 DRN2 Drain of self configurable channel 2

15 SRC2 Source of self configurable channel 2

12 DRN3 Drain of self configurable channel 3

13 SRC3 Source of self configurable channel 3

2 DRN4 Drain of channel 4

16 DRN5 Drain of channel 5

14 DRN6 Drain of channel 6

11 DI

SPI data in:

The input requires CMOS logic levels and receives serial data from the

microcontroller. The data is a 16-bit control word and the most significant bit

(MSB, bit 7) is transferred first.

9DO

SPI data out:

The diagnosis data is available via the SPI and this tristate-output. The output

remains in tristate, if the chip is not selected by the input CSN (CSN = high).

7CSN

SPI chip select not (active low):

This input is low active and requires CMOS logic levels. The serial data transfer

between the L99MC6 and microcontroller is enabled by pulling the input CSN to

low-level.

10 SCK

SPI serial clock input:

This input controls the internal shift register of the SPI and requires CMOS logic

levels.
