Battery Linear Charger
Charge status indicator
AME2056 has two status indicators CHRG and STDBY. When the charger is operating in charging status, the CHRG
and STDBY outputs enter strong pull-down and high impedance status, respectively. If the battery is in full status, the
CHRG and STDBY outputs enter high impedance and strong pull-down, respectively. When the TEMP pin voltage is
greater than V_TEMP-H or lower than V_TEMP-L, the CHRG and STDBY outputs enter high impedance.
When the TEMP pin is short to ground for disable the temperature protection and the battery is not to connect BAT pin,
the light of CHRG and STDBY are flicker and bright, respectively.

Thermal Protection
The internal thermal feedback loop of AME2056 reduces the charging current when the die temperature rises above
approximately 145^oC. The function protects the AME2056 from excessive temperature and allow user to push the limits
of the power handing capability without risk of damaging AME2056.
