(1) See EVAL-05 Operational Modes on page 4 for optional connections to VBAT. The EVAL05 module is sensitive to electrostatic discharge (ESD) and must be handled accordingly. In cases where the EVAL-05 module is removed from its original packaging, it is a requirement to maintain the same type of anti-static, non-conductive packaging to prevent discharge of the on-board EnerChips. Do not store the EVAL-05 in conductive black foam, as it will discharge and destroy the EnerChips on the module.
©2009-2010 Cymbet Corporation • Tel: +1-763-633-1780 • www.cymbet.com DS-72-09 Rev A Page 4 of 4 Using the EVAL-05 Place the 24-pin EVAL-05 module into solderless breadboard or socket with pin 1 in pin 1. • Note that if only one EnerChip CC is to be evaluated at a time, only pins 1 to 12 need to be connected on • the test board. With board pin 1 in socket pin 1, the CBC3150 is accessible. To access the CBC3112, turn the EVAL-05 180 degrees and place EVAL-05 pin 13 in socket pin 1. Tie V• BAT to VCHG on the test board. When operating under main power, LED D1 (CBC3150) or D2 (CBC3112) will be illuminated. When • operating in battery backup mode, LED D1 (CBC3150) and D2 (CBC3112) will not be illuminated. Tie V• MODE to VDD or GND depending the system voltage and the desired switchover voltage. Optionally, use a resistor divider. See the CBC3112 or CBC3150 datasheets for switchover voltage details. Tie the ENABLE pin to V• DD. Tie V• OUT to VDD of a microcontroller or any device requiring power backup. Tie the RESET pin to the interrupt pin of a microcontroller if desired. When operation is under battery • backup mode, the LED will not be illuminated. Allow the EnerChip CC to charge for at least 30 minutes before attempting to use backup power.• Monitor V• BAT for battery voltage and monitor VOUT for output voltage to the system. Place current meter between V• BAT and VCHG to monitor battery charging current if desired. Disconnect V• DD and the RESET pin will go low and system will switchover to battery backup mode.

EVAL-05 Operational Modes The CBC-EVAL-05 board can be used in seven different ways: CBC3150 only - Connect to pins 1-12. 1. CBC3112 only - Connect to pins 13-24 or rotate the EVAL-05 so that pin 13 is inserted into socket pin 1 2. and connect to pins 1-12 on EVAL-05. CBC050 only - the EnerChip 50 µAh battery is tested alone. Do not connect pins 1 and 4 together; pin 1 is 3. the positive EnerChip terminal and can be charged and discharged independently of the integrated battery management circuitry. See the CBC050 data sheet for EnerChip operating and use conditions. CBC012 only - the Enerchip 12 µAh battery is tested alone. Do not connect pins 13 and 16 together; pin 4. 13 is the positive EnerChip terminal and can be charged and discharged independently of the integrated battery management circuitry. See the CBC012 data sheet for EnerChip operating and use conditions. CBC3150 controlling the CBC012 - The CBC3150 can be used to control external EnerChips, including the 5. CBC012 embedded in the CBC3112 package on board the EVAL-05. This is accomplished by connecting pin 4 (VCHG) to pin 13 (VBAT). CBC3112 controlling the CBC050 - The CBC3112 can be used to control external EnerChips, including the 6. CBC050 embedded in the CBC3150 package on board the EVAL-05. This is accomplished by connecting pin 16 (VCHG) to pin 1 (VBAT). CBC3112 and CBC3150 simultaneously - Connect the two 7. VBAT pins (1 and 13) together and tie them to EITHER VCHG pin (not both). Leave the other VCHG disconnected from the circuit.
