NAME
FUNCTION
10
A5
CTLI
TEC Current-Control Input. Sets TEC current. Center point is 1.50V (no TEC current). The
current is given by:
I
TEC
= (V
OS1
- V
CS
) / R
SENSE
= (V
CTLI
- 1.50) / (10 x R
SENSE
). When (V
CTLI
- V
REF
) > 0,
then V
OS2
> V
OS1
> V
CS
.

A6
B6
GND
V
DD
Analog Ground. Start connect to PGND at underside exposed pad for QFN package.
Analog Supply Voltage Input. Bypass V
DD
to GND with a 1μF ceramic capacitor.
For MAX8520: Analog FREQ Set Pin (see the
Switching
Frequency
section).
13
C5
FREQ
For MAX8521: Digital FREQ Selection Pin. Tie to V
DD
for 1MHz operation, tie to GND for
500kHz operation. The PWM oscillator can synchronize to FREQ by switching at FREQ
between 700kHz and 1.2MHz.
14
D4, D5, D6
PGND2
Power Ground 2. Internal synchronous rectifier ground connection. Connect all PGND
pins together at the power ground plane.
15
16
E5, E6
F5, F6
LX2
PV
DD
2
Inductor Connection. LX2 is high impedance in shutdown.
Power Input 2. Connect all PV
DD
inputs together at the V
DD
power plane.
Current-Sense Input. The current through the TEC is monitored between CS and OS1. The
maximum TEC current is given by 150mV/R
SENSE
and is bipolar.
17
F4
CS
18
C6
OS2
Output Sense 2. OS2 senses one side of the differential TEC voltage. OS2 is a sense
point, not a power output. OS2 discharges to ground in shutdown.
19
F3
OS1
Output Sense 1. OS1 senses one side of the differential TEC voltage. OS1 is a sense
point, not a power output. OS1 discharges to ground in shutdown.
20
F1, F2
PV
DD
1
Power Input 1. Connect all PV
DD
inputs together at the V
DD
power plane.
Ground. Additional ground pads aid in heat dissipation. Short to either GND or PGND
plane.
B2, B5,
C3, C4
GND2
B3, B4
E3, E4
N.C.
No Connect. Connect no-connect pads to GND2 to aid in heat dissipation.
