ZHCS861B April 2012 – June 2015 PGA450-Q1
PRODUCTION DATA.
The PGA450-Q1 can operate from a 7- to 18-V power supply. The device can be connected directly to a battery through a reverse battery-protection diode. The ramp-down rate of the power supply must be faster than 1V/ms so that the AVDD UV flag remains valid. Read SLDA028 for a full description of this requirement.
The VREG pin can be programmed to regulate from 4.7 to 8.4 V. The VPWR supply voltage must be 2-V greater than the VREG voltage to ensure proper regulation.
