CBC-EVAL-09 EnerChip EP Universal EH Eval Kit
EVAL-09 Module Connector and Test Point Explanations
The purpose and use of the connectors identified in Figure 3 and in the previous tables are:
J1, J2, J8, J11, J13, J14 Connectors - not user accessible.
J3 Connector - EnerChip EP pins 1-19 probe points and access vias.
J4 Connector - EnerChip EP pins 20-38 probe points and access vias.
J5, J6 Connectors - EVAL-09 debug interface connectors for development system access. Contact Cymbet
Applications Engineering for additional details if required.
J7 Connector - Bypass diode circular pad trace to select an optional external rechargeable lithium battery
with 4.1V charging voltage.
J9 Connector - Six pin right angle connector for serial port, Vout and Ground. Normally used for connection to
TI eZ430-RF2500 wireless end device or another target system.
J10 Connector - Five pin vertical connector for user access to serial port, Vout and Ground.
J12 Connector - Access vias for an optional external rechargeable lithium battery with 4.1V charging voltage.
J15 Connector - High Voltage DC Input from EH Transducer such as a thermoelectric generator (TEG).
J16 Connector - High Voltage AC Input 1 normally used by a piezoelectric EH transducer.
J17 Connector - High Voltage AC Input 2 normally used by a piezoelectric EH transducer .
J18 Connector - Low voltage DC Input normally used by a photovoltaic cell.
J19 Connector - Low voltage AC Input normally used by a thermoelectric generator or electromagnetic
generator.
Cable Assembly - A 5-conductor cable with a header connector at each end is provided with CBC-EVAL-09 to
facilitate connection between the J5 connector and a 5-pin header on the user’s board.
TP1 - the output of the boost converter or FLYBACK converter capacitor. Typical value is 4.06V.
TP2 - EPVCC - Voltage used to power the CBC915 device should be 3.6V
TP3, TP3, TP5 - Ground
TP6 – VCAP – voltage of the output capacitor should be 3.6V
TP7– VOUT – output voltage to the target system should be 3.6V
TP8 – VBAT – output of battery cut-off circuit should be 4.06V
TP9 – VEC – EnerChip output voltage feeding battery cutoff circuit should be in the range of 4.06VDC to
3.0VDC. Caution: do not leave voltmeter or scope probes attached to this TP. Will discharge EnerChip.
TP10 – HV V In – DC voltage from the HV DC In or HV AC1 IN or HV AC2 IN ports
TP11 – V In – DC voltage from the DC In or AC1 IN ports
