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 HL7519 modules support separate VBATT and
VBATT_PA connection if requirements below are fulfilled.
2.1. Power Supply
The AirPrime HL7519 module is supplied through the VBATT signal with the following characteristics.

This value has to 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.
2.2. VGPIO
The VGPIO output can be used to:
Pull-up signals such as I/Os
Supply the digital transistors driving LEDs
The VGPIO output is available when the AirPrime HL7519 module is switched ON.
