com/ MT6305B Confidential Information Product Change Notice Original product name : MT6305N/FT New identification : MT6305BN/CY Change Contents Item 1 Change type New function Description Use pin#3 (original NC pin) to program Provide alternative VCORE/VRTC.
VCORE/VRTC=1.
8V/1.
5V VCORE/VRTC voltas pin#3 is floating.
age.
VCORE/VRTC=1.
2V/1.
2V as pin#3 is GND.
CHRIN can be up to 15V but the charger will be off automatically when CHRIN>Vac_limit.
The spec.
of Vac_limit is 8~9.
5V.
It can’ t be used with external linear charger.
Change pin#29 (original NC pin) to VREF.
Better power/ground plan.
Change pin#30 (original VREF) to NC pin.
Better power/ground It can be connected to a capacitor, GND or plan.
floating.
Remove the VASEL (pin44) and VMSEL (pin45) internal pull high/low definition.
Save power.
To protect internal device.
2 Device protection 3 4 Pin configuration Pin configuration 5 Pin description Special request on PCB Ø It must use X5R-type decoupling capacitor on VTCXO and VA LDO outputs for good performance against temperature variation.
Ø In VCORE/VRTC=1.
8V/1.
5V application, no special change is required to use MT6305BN/CY.
It’ s fully compatible with the PCB for MT6305N/FT.
If user would like to configure VCORE/VRTC=1.
2V/1.
2V, just tie pin#3 to GND via a 0-Ohm resistor.
