MAX13173E Pin Description (continued)
PIN NAME FUNCTION
37 C1+
V DD Charge-Pump Flying-Capacitor Positive Terminal. Connect a 1µF ceramic capacitor
between C1+ and C1-.
38 V DD
Charge-Pump Positive-Supply Output. Connect a 4.7µF ceramic capacitor from V DD to ground
as close as possible to the device.
— EP
Exposed Pad. Internally connected to V EE . Connect to a large V EE plane to maximize thermal
performance, not intended as an electrical connection point. Does not share the same plane as
the MAX13171E.

15 V L Logic-Supply Reference Input. V L determines the voltage level of the logic interface.
16 V
EE
Negative Supply Voltage. Bypass V EE to GND with a 0.1µF capacitor. Connect to V EE from the
MAX13173E.
17 V DD
Positive Supply Voltage. Bypass V DD to GND with a 0.1µF capacitor. Connect to V DD from the
MAX13173E.
19 V CC Supply Voltage. Bypass V CC to GND with a 0.1µF capacitor as close as possible to the device.

32 DCE/DTE DCE/DTE Mode-Select Input
33 LATCH
Latch Signal Input. When LATCH is low, the input latches are transparent. When LATCH is high,
the data at the mode-select inputs are latched.
34 M2 Mode-Select Input 2
35 M1 Mode-Select Input 1
36 M0 Mode-Select Input 0
37 R1C Load 1, Center Tap
— EP
Exposed Pad. Internally connected to V EE . Connect to a large V EE plane to maximize thermal
performance, not intended as an electrical connection point. If V EE is powered from the
MAX13173E’s V EE , planes can be shared.
