25 / 53 page  4116369 Rev 9.0 September 04, 2017 25 3. Detailed Interface Specifications Note: If not specified, all electrical values are given for VBATT=3.7V and an operating temperature of 25°C. For standard applications, VBATT and VBATT_PA must be tied externally to the same power supply. For some specific applications, AirPrime HL7548 and HL7588 modules support separate VBATT and VBATT_PA connection if requirements below are fulfilled. 3.1. Power Supply The AirPrime HL7548 and HL7588 modules are supplied through the VBATT signal with the following characteristics. Table 7. Power Supply Supply Minimum Typical Maximum VBATT voltage (V) 3.2* 3.7 4.5 VBATT_PA voltage (V) Full Specification 3.2* 3.7 4.5 VBATT_PA voltage (V) Extended Range 2.8 3.7 4.5 * This value must be guaranteed during the burst. Note: Load capacitance for VBATT is around 32µF ± 20% embedded inside the module. Load capacitance for VBATT_PA is around 10µF ± 20% embedded inside the module. 3.2. Current Consumption The following table lists the current consumption of the AirPrime HL7548 and HL7588 at different conditions. Note: The following data is with USB disconnected to achieve the lowest current consumption. An additional 0.6mA will be consumed if USB is connected. Typical values are defined for VBATT/VBATT_PA at 3.7V and 25°C, for 50Ω impedance at all RF ports. Maximum values are provided for VSWR3:1 with worst conditions among supported ranges of voltages and temperature. Table 8. Current Consumption Parameter Minimum Typical Maximum Unit Off mode 95 110 202 µA Sleep mode – LTE DRX = 1.28s USB = disconnected Band 2 1.2 1.4 6.2 mA Band 4 1.2 1.4 6.2 mA Band 5 1.2 1.4 6.2 mA Band 13* 1.2 1.4 6.2 mA Band 17 1.2 1.4 6.2 mA |
