GND
1
Digital and analog low power GND

O (VS)
High side P-channel driver output. Becomes driven to VHS to switch
on MOSFET.

I (VS)
Sensing input for bridge outputs. Used for short to GND protection.
May be tied to VS if unused.

O 5V
Low side MOSFET driver output. Becomes driven to 5VOUT to switch
on MOSFET.

Sense resistor input of chopper driver.
SRB

5VOUT
9
Output of internal 5V linear regulator. This voltage is used to
supply the low side drivers and internal analog circuitry. An
external capacitor to GND close to the pin is required. Place the
capacitor near to pin 9 and pin 13. 470nF ceramic are sufficient for
most applications, an additional tantalum capacitor (10µF or more)
improves performance with high gate charge MOSFETs.
