I
LVTTL
Reset: Reset Pin (active low)
This pin should connect to ground through a 0.1
F filter capacitor and a 10k resistor to
VDD. In application it can also directly connect to one output pin from microcontroller (MCU).
AVDD
1
I
Power
AVDD: Analog Power Supply
This pin provides power supply to the analog part. This pin should connect to DVDD and be
decoupled with a 0.1
F capacitor.
DVDD
48
I
Power
DVDD: Digital Power Supply
This pin provides power supply to the digital part. It should be decoupled with a 10
F capac-
itor and a 0.1
F capacitor.
VDD18
42, 43
P
Power
VDD18: Digital Power Supply (1.8 V)
These two pins should be connected together and connected to ground through a 10
F
capacitor.

I1P: Positive Input for Phase A Current
I1N: Negative Input for Phase A Current
These pins are differential inputs for phase A current.
Note: I1 to phase A and I3 to phase C mapping can be swapped by configuring the I1I3Swap
bit (b13, MMode0).

I3P: Positive Input for Phase C Current
I3N: Negative Input for Phase C Current
These pins are differential inputs for phase C current.
Note: I1 to phase A and I3 to phase C mapping can be swapped by configuring the I1I3Swap
bit (b13, MMode0).

I4P: Positive Input for N Line Current
I4N: Negative Input for N Line Current
These pins are differential inputs for N line current.
Vref
11
O
Analog
Vref: Output Pin for Reference Voltage
This pin should be decoupled with a 10
F capacitor, possibly a 0.1F ceramic capacitor and
a 1nF ceramic capacitor.
V1P

I
OSC
OSCI: External Crystal Input
OSCO: External Crystal Output
A 16.384 MHz crystal is connected between OSCI and OSCO. There are two on-chip capac-
itor, therefore no need of external capacitors.
