Table 2. Pin definitions and functions
Pin Symbol Function
1 GND Ground. Reference potential, connected to slug.
2 GNDD Digital ground. Reference potential.
3V
CCD
Logic voltage supply 3.3 V/5 V: for this input a ceramic capacitor as
close as possible to GND is recommended.
4V
CC
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.
6DIR
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.
8CSN
Chip select not input: this input is low active and requires CMOS logic
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.
