DESCRIPTION
EXTERNAL COMPONENTS OR CONNECTIONS
POWER AND GROUND
CP1
30
I/O
Charge pump flying capacitor
Connect a 0.1-μF 35-V capacitor between CP1 and CP2
CP2
29
I/O
GND
26, PPAD
I
Ground reference. Terminal 26 and the
Power Pad are internally connected.
Connect to board GND
VCP
28
I/O Charge pump storage capacitor
Connect a 1-μF 35-V ceramic capacitor to VM
VINT
25
I/O
Internal 1.8-V core voltage regulator
bypass
Bypass to GND with a 1-μF 6.3-V ceramic capacitor
VM
27
I Motor supply voltage
Connect to motor supply voltage.
Bypass to GND with a 0.1-μF ceramic capacitor, plus a
large electrolytic capacitor (47 μF or larger is
recommended), with a voltage rating of 1.5× to 2.5× VM.
VREG
24
O
5-V regulator output. Active when
ENABLEn is active.
Bypass to GND with a 0.1-μF 10-V ceramic capacitor.
Can provide 5-V power to Hall sensors.
VSW
7
Switched VM power output. When
O ENABLEn is active, VM is applied to this
terminal.
Can be used for powering Hall elements, along with
added series resistance.
CONTROL
BRAKE
20
I
Causes motor to brake. Polarity is
programmable. Internal pulldown resistor.
PWM
The clock input, used in clock frequency
19
I mode and clock PWM mode. Internal
pulldown resistor.
DIR
21
I
Sets motor rotation direction. Internal
pulldown resistor.
ENABLEn
22
I
Enables and disables the motor – active
low. Internal pulldown resistor.
FAULTn
Fault indicator – active low when
17
OD overcurrent, overtemperature, or rotor stall
detected. Open-drain output.
HALLOUT
16
OD
Outputs a TACH signal generated from the
Hall U sensor. Open-drain output.
(1) I = input, O = output, OD = open-drain output, I/O = input/output
