Preliminary Datasheet
TinyShieldTM BATTERY PROTECTOR AND MOSFET COMBO
General Description
AZ6002
CR6002
The CR6002 is a member of CARETTA's TinyShieldTM
Battery Protector product family. It uses the company's
properitary patent pending (US & China) smart
switch technology to implement on-chip MOSFETs thus
reduces manufacturing cost and increases reliability.
The device is designed to protect single cell Li-Ion and
Li-Pol battery packs from either overcharge, overdis-
charge, or overcurrent.
The device contains all required protection control cir-
cuits together with very low resistance MOSFETs to
minimize the number of external components. It incor-
porates overcharge voltage and current protections,
overdischarge voltage and current protections, over-
temperature protection, short circuit protection and
operates with very low power.
The device is not only targeted for digital cellular
phones, but also for any other Li-Ion and Li-Pol battery-
powered information appliances requiring long-term
battery life time.

Accuracy: ± 25mV
· Overdischarge Detection Voltage: 2.0V to 3.0V
(12.5mV step). Accuracy: ± 25mV
· Overdischarge Hysteresis Voltage: 0.0V to 0.7V.
Accuracy: ± 25mV
10. Low current consumption
· Operation mode: 2.0µA typ., 4.0µA max.
· Power-down mode: 0.1µA max.
11. Small outline MSOP-8 Package
12. RoHS Compliant and Lead (Pb)-Free
Features
Applications
1. No External MOSFETs Required
2. Equivalent of 29mΩ RDS(ON) on-chip MOSFET
3. Only one external capacitor required in application
