  • Page 22: Interface Application

    Smart Machine Smart Decision Interface Application Power Supply Pin 55, pin 56 and pin 57 are VBAT power input. On VBAT pads, the ripple current up to 0.6A typically due to LTE CAT-M1emission burst and up to 2A typically due to GSM/GPRS emission burst (every 4.615ms). It may cause voltage drop. So the power supply for these pads must be able to provide sufficient current up to more than 2A in order to avoid the voltage drop is more than 300mV.

  • Page 23: Power Supply Design Guide

    Smart Machine Smart Decision 3.1.1 Power Supply Design Guide Make sure that the voltage on the VBAT pins will never drop below 3.0V, even during a transmit burst, when current consumption may rise up to 2A. If the voltage drops below 3.0V, module will be work abnormally.
