3.3.2 VBAT Interface

When the MC509 module works normally, power is supplied through the VBAT pins and the voltage ranges from 3.3V to 4.2V (typical value: 3.8V). The 145-pin LGA provides two VBAT pins and sixteen GND pins for external power input. To ensure that the MC509 module works normally, all the pins must be used efficiently.

When the MC509 module is used for different external applications, pay special attention to the design for the power supply. When the MC509 module transmits signals at the maximum power, the transient current may reach the transient peak value of about 1.5A due to the differences in actual network environments. In this case, the VBAT voltage drops. Make sure that the voltage does not decrease below 3.3V in any case. Otherwise, exceptions such as restart of the MC509 module may occur.

A low-dropout (LDO) regulator or switch power with current output of more than 1.5A is recommended for external power supply. Furthermore, a 220uF or above energy storage capacitor is connected in parallel at the power interface of the MC509 module.
