Fast Charge Battery Manager with Power Path and
USB Compatibility
GENERAL DESCRIPTION
The ADP5065 charger is fully compliant with the USB 2.0, USB
3.0 and USB Battery Charging Specification 1.1 and enables
charging via the mini-USB VBUS pin from a wall charger, car
charger, or USB Host port.
The ADP5065 operates from a 4V to 5.5V input voltage range
but is tolerant up to 20V. These alleviate the concerns of the
USB bus spiking during disconnect or connect scenarios.
The ADP5065 also features an internal FET between the DCDC
charger output and the battery. This permits Battery Isolation
and hence System powering under a dead battery or no battery
scenario which allows for immediate system function on
connection to a USB power supply
Based on the type of USB source detected by an external the
USB detection chip, the ADP5065 can be set to apply the
correct current limit for optimal charging and USB compliance.
PACKAGE AND EXTERNALS
The ADP5065 comes in a very small and low profile WLCSP-20
(0.5 mm pitch spacing) package.
The overall solution requires only 5 small, low profile external
components consisting of 4 ceramic capacitors (1 of which is
the battery filter capacitor), 1 multi-layer inductor and 1
optional dead battery situation default setting resistor.
This enables a very small PCB area to provide an integrated and
performance enhancing solution to USB battery charging and
power rail provision
