CONFIDENTIAL
15
GND
System Ground. IC reference and bias ground.
16
VID_SEL
D-I
Select pin for the different VID modes. For VR10, this signal needs to be grounded. For
VR11.1, the signal needs to be floating (>0.8 V and <1.8 V). For AMD PVI/SVI compliance
the pin needs to be tied high (>1.8 V).
17
TM
A-I
Thermal monitor input pin. Its input is connected to a negative thermal coefficient (NTC)
thermistor network to set the temperature thresholds for VR_HOT and VR_FAN. The TM pin
is also for internal temperature compensation.
18
VR_HOT
D-O
Over-temperature alarm signal logical output. Signal is active high when the TM pin (thermal
monitor) passes a set threshold. This pin is open-drain.
19
VR_FAN
D-O
Over-temperature warning signal logical output. Signal is active high when the TM pin
(thermal monitor) passes a set threshold. This pin is open-drain.
20
PWM4
A-I/O
Dual function pin. In normal operation, it will act as the pulse width modulated 3-stateable
output signal for an external fourth channel driver. On power-up, this pin will also act as a
3-state input pin to select the number of required phases.
21
GND
System Ground. IC reference and bias ground.
22
NC
No Connect
23
VDD
P-I
+5V (nominal) supply pin for “l(fā)ower” voltage circuits.
24
BOOST3
P-I
Voltage supply for the upper power MOSFET gate drive. An external bootstrap capacitor is
also required. An internal diode is connected to this pin for the bootstrap charge.
25
UGATE3
A-I/O
Connect this pin to the gate of upper power MOSFET 3
26
PHASE3
A-I/O
Return path for the corresponding upper power MOSFET gate driver for phase 3.
27
GND3
GND
Gate Driver 3 Ground.
28
LGATE3
A-I/O
Connect to the gates of lower power MOSFET 3.
29
PVCC
P-I
One of three supply input pins for the corresponding channel MOSFET drive.
Connect to +12V supply.
30
BOOST2
P-I
Voltage supply for the upper power MOSFET gate drive. An external bootstrap capacitor is
also required. An internal diode is connected to this pin for the bootstrap charge.
31
UGATE2
A-I/O
Connect this pin to the gate of upper power MOSFET 2.
32
PHASE2
A-I/O
Return path for the corresponding upper power MOSFET gate driver for phase 2.
33
GND2
GND
Gate Driver 2 Ground.
34
LGATE2
A-I/O
Connected this pin to the gates of lower power MOSFET 2.
35
PVCC
P-I
One of three supply input pins for the corresponding channel MOSFET drive.
Connect to +12V supply.
36
PVCC
P-I
One of three supply input pins for the corresponding channel MOSFET drive.
Connect to +12V supply.
37
LGATE1
A-I/O
Connected to the gates of lower power MOSFET 1.
38
GND1
GND
Gate Driver 1 Ground.
39
PHASE1
A-I/O
Return path for the corresponding upper power MOSFET gate driver for phase 1.
40
UGATE1
A-I/O
Connect this pin to the gate of upper power MOSFET 1.
41
BOOST1
P-I
Voltage supply for the upper power MOSFET gate drive. An external bootstrap capacitor is
also required. An internal diode is connected to this pin for the bootstrap charge.
42
VDD
P-I
+5V (nominal) supply pin for “l(fā)ower” voltage circuits.
43
CSN1
A-I
Phase 1 current sense - negative input.
44
CSP1
A-I
Phase 1 current sense - positive input.
