Charge Pump Pins

Booster Interface

EZ-OTG has an on-chip power booster circuit for use with
power supplies that range between 2.7V and 3.6V. The
booster circuit boosts the power to 3.3V nominal to supply
power for the entire chip. The booster circuit requires an
external inductor, diode, and capacitor. During power down
mode, the circuit is disabled to save power.

Figure 2

shows

how to connect the booster circuit.

Component details:

• L1: Inductor with inductance of 10 µH and a current rating

of at least 250 mA

• D1: Schottky diode with a current rating of at least 250 mA

• C1: Tantalum or ceramic capacitor with a capacitance of at

least 2.2 µF

Figure 3

shows how to connect the power supply when the

booster circuit is not being used.

Crystal Interface

The recommended crystal circuit to be used with EZ-OTG is
shown in

Figure 4

. If an oscillator is used instead of a crystal

circuit, connect it to XTALIN and leave XTALOUT uncon-
nected. For further information on the crystal requirements,
see
