voltage. The IC is designed to monitor input voltage, input current, and battery voltage. When any of the monitored parameters are over the threshold, the IC removes
the power from the charging system by turning off an internal switch. All protections also have deglitch time
against false triggering due to voltage spikes or current
transients. The APL3205A/B also provide over-temperature protection, a FAULT output pin to indicate the fault
conditions, and the EN pin to allow the system to disable
the IC.

Note : ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish;
which are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD020C for MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and
halogen free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed
1500ppm by weight).

APL3205A/B
Function Description (Cont.)
Powering an Accessory Device
In some applications, such as USB On-The-Go, users need to power an accessory device by using the portable
device’s battery through the jack holes of AC adapter. The APL3205 provide reverse current flow path from OUT to IN.
If VOUT > VPOR + 0.7V, FET Q1 is turned on, and the reverse current does not flow through the diode but through Q1. Q1
will then remain ON as long as VOUT > VPOR-VPOR_HYS + RDS_ON*ISUPPLY. Within this voltage range, the reverse current
capability is the same as the forward capability, 1.5A. It should be noted that there is no overcurrent protection in this
direction.
