Product Details

Description



Features:

• Small (5.5mm x 22.5mm) two sided board with only two components.
• Integrated low impedance MOSFET switch and current sensor (50m typical)
• Overcharge protection, with built-in 1.5 second time delay (typical)
• High accuracy ±1.0% tolerance on Overcharge threshold (over temperature)
• Four standard Overcharge thresholds are available (4.20, 4.25, 4.30 4.35V)
• Over-discharge protection, with built-in 15msec time delay (typical)
• Overload/short circuit protection with built-in 1.5msec time delay (typical)
• Automatic recovery from short circuit when load is removed
• Reverse charger protection (up to 8V)
• Runaway charger protection (up to +16V)
• Overtemp protection
• Low operating current of 5A (typical)
• Low Sleep mode current of 1.5A (typical)



Description

The UCC3952 demo board provides complete protection for a single Lithium-ion cell, including Overcharge, Over-discharge and short circuit protection. The application schematic is shown in Fig. 1 and a component placement is shown in Fig. 2. A list of materials, giving the component part numbers and case sizes is given in Table 1. Note that the UCC3952, using an internal MOSFET switch, requires only a single external decoupling capacitor to provide a complete protection solution.
