Table 2. Pin definitions and functions

Pin

Symbol

Function

1

GND

Ground. Reference potential, connected to slug.

2

GNDD Digital ground. Reference potential.

3

VCCD

Logic voltage supply 3.3 V/5 V: for this input a ceramic capacitor as

close as possible to GND is recommended.

4

VCC

Analog voltage supply 3.3 V/5 V: for this input a ceramic capacitor as

close as possible to GND is recommended.

5

EN

Enable input. The enable input has a pull-down resistor.

6

DIR

Direction select input for H-bridge control. This input has a pull-down

current.

7

PWM

PWM input for H-bridge control. This input has a pull-down current.

Chip select not input: this input is low active and requires CMOS logic

8

CSN

levels. The serial data transfer between L99H01 and microcontroller is

enabled by pulling the input CSN to low-level. This input has a pull-up

current.
