CBC-EVAL-05B EnerChip CC Evaluation Kit EnerChip™ CC CBC3105, CBC3112 & CBC3150 Eval Kit Overview The EnerChip™ CC EVAL-05B Evaluation Kit is used to demonstrate the capabilities of EnerChip Solid State Batteries and the EnerChip CC with Integrated Battery Management capabilities. The kit can be used to demonstrate: 1 ) EnerChip battery standalone , 2) either EnerChip CC device or 3 ) the EnerChip CC in parallel with the another EnerChip battery. Figure 2: EVAL-05B Boards - CBC3150/CBC3112 board on left and the CBC3105-EVAL-05 board on the right CBC-EVAL-05B EVAL Kit The EnerChip CC is the world’s first smart rechargeable Solid State Battery. It is an integrated solution that provides battery backup and power management for systems requiring power backup and/or rechargeable energy storage. A single EnerChip CC can charge up to 10 additional EnerChips connected in parallel. Figure 1: EnerChip CC Block Diagram EnerChip CC Applications • Standby supply for non-volatile SRAM, real-time clocks, controllers, supply supervisors, and other system-critical components. • Wireless sensors and RFID tags and other powered, low duty cycle applications. • Localized power source to keep microcontrollers and other devices alert in standby mode. • Power bridging to provide back-up power to system during exchange of main batteries. • Consumer appliances that have real-time clocks; provides switchover power from main supply to backup battery. • Business and industrial systems such as: network routers, point-of-sale terminals, singleboard computers, test equipment, multi-function printers, industrial controllers, and utility meters • Energy Harvesting by coupling the EnerChip with energy transducers such as solar panels. There are 2 boards in the EVAL-05B kit as shown in Figure 2 above: The first board has a CBC3112 and a CBC3150. This evaluation board utilizes a 24pin DIP format. The second board has a CBC3105. The CBC3105-EVAL-05 evaluation board utilizes a 16-pin DIP format. Both boards have standard 0.6 inch pin width with 100mil center pin spacing. Either EVAL-05B board can be inserted into a solderless breadboard or 24-pin socket for easy experimentation. During normal operation, the EnerChip CC charges itself with a controlled voltage using an internal charge pump that operates from 2.5V to 5.5V. An ENABLE pin allows the designer to activate and deactivate the charge pump using an external control line in order to minimize current consumption and take advantage of the fast recharge time of the EnerChip. A power fail detect indication is available via RESET pin. The CBC3105, CBC3112 and CBC3150 data sheets contain complete specifications and application circuits for each EnerChip CC device. ©2013 Cymbet Corporation • Tel: +1-763-633-1780 • www.cymbet.com DS-72-26 Rev B Page 1 of 7 EnerChip CBC-EVAL-05B Input/Ouput Descriptions and Pin-outs for CBC3112/CBC3150 board (1) Pin Number Label Description 1 VBAT Positive Battery Terminal - Tie to Pin 4 (1) 2 VOUT System Voltage 3 VDD Input Voltage 4 VCHG Battery Charge Voltage - Tie to Pin 1 and/or Optional EnerChip(s) 5 ENABLE Charge Pump Enable 6 VMODE Mode Select for Battery Switchover Threshold 7 GND System Ground 8 RESET Reset Signal (Active Low) 9 CP Flying Capacitor Positive 10 CN Flying Capacitor Negative 11 NC No Connection 12 NC No Connection 13 VBAT Positive Battery Terminal - Tie to Pin 16 (1) 14 VOUT System Voltage 15 VDD Input Voltage 16 VCHG Battery Charge Voltage - Tie to Pin 13 and/or Optional EnerChip(s) 17 ENABLE Charge Pump Enable 18 VMODE Mode Select for Battery Switchover Threshold 19 GND System Ground 20 RESET Reset Signal (Active Low) 21 CP Flying Capacitor Positive 22 CN Flying Capacitor Negative 23 NC No Connection 24 NC No Connection See EVAL-05 Operational Modes on page 6 for optional connections to VBAT.

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. ©2013 Cymbet Corporation • Tel: +1-763-633-1780 • www.cymbet.com DS-72-26 Rev B Page 2 of 7 EnerChip CBC-EVAL-05B EVAL-05 Evaluation Board Schematic The CBC-EVAL-05 board is configured symmetrically so that a single external circuit can be used to evaluate the CBC3150 when the board is plugged into the DIP socket in the pin 1 to pin 1 orientation, and the CBC3112 when the board is rotated 180 degrees. Pins 1-12 pertain to the CBC3150. Pins 13-24 pertain to the CBC3112. A circuit schematic of CBC-EVAL-05 is shown in Figure 3. Figure 4 is a typical application circuit.

CBC3150 only - Connect to pins 1-12. 2. CBC3112 only - Connect to pins 13-24 or rotate the EVAL-05 so that pin 13 is inserted into socket pin 1 and connect to pins 1-12 on EVAL-05. 3. CBC050 only - the EnerChip 50 µAh battery is tested alone. Do not connect pins 1 and 4 together; pin 1 is 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. 4. CBC012 only - the Enerchip 12 µAh battery is tested alone. Do not connect pins 13 and 16 together; pin 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. 5. CBC3150 controlling the CBC012 - The CBC3150 can be used to control external EnerChips, including the CBC012 embedded in the CBC3112 package on board the EVAL-05. This is accomplished by connecting pin 4 (VCHG) to pin 13 (VBAT). 6. CBC3112 controlling the CBC050 - The CBC3112 can be used to control external EnerChips, including the CBC050 embedded in the CBC3150 package on board the EVAL-05. This is accomplished by connecting pin 16 (VCHG) to pin 1 (VBAT). 7. CBC3112 and CBC3150 simultaneously - Connect the two VBAT pins (1 and 13) together and tie them to EITHER VCHG pin (not both). Leave the other VCHG disconnected from the circuit. Using the EVAL-05 board • 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 VBAT 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 VMODE 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 VDD. • Tie VOUT 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 VBAT for battery voltage and monitor VOUT for output voltage to the system. • Place current meter between VBAT and VCHG to monitor battery charging current if desired. • Disconnect VDD and the RESET pin will go low and system will switchover to battery backup mode. Adding the CBC3105-EVAL-05 Evaluation Board to the CBC-EVAL-05 The CBC-EVAL-05B kit combines the existing CBC-EVAL-05 24-pin DIP board with the new CBC3105-EVAL-05 16pin DIP board and is intended to test the EnerChip CC CBC3105 in standalone mode. ©2013 Cymbet Corporation • Tel: +1-763-633-1780 • www.cymbet.com DS-72-26 Rev B Page 4 of 7 EnerChip CBC-EVAL-05B Input/Ouput Descriptions and Pin-outs for CBC3105-EVAL-05 board (1) Pin Number Label Description 1 VBAT Positive Battery Terminal 2 NC No Connection 3 NC No Connection 4 NC No Connection 5 VCHG Battery Charge Voltage - Tie to Pin 1 and /or Optional EnerChip(s) 6 NC No Connection 7 VOUT System Voltage 8 GND System Ground 9 ENABLE Charge Pump Enable 10 RESET Reset Signal (Active Low) 11 NC No Connection 12 CP Flying Capacitor Positive 13 CN Flying Capacitor Negative 14 VMODE Mode Select for Battery Switchover Threshold 15 GND System Ground 16 VDD Input Voltage See CBC3105-EVAL-05 Operational Modes on page 5 for optional connections to VBAT.

Figure 5: CBC3105 -EVAL-05 Circuit Schematic CBC3105 Application Circuit The CBC3105 can be used for secondary power backup for Real Time Clocks and Microcontrollers (MCUs). Note: that the pin-out of the CBC3105 is different than the CBC3112 and CBC3150 and should be taken into consideration when designing products with the CBC3105.
