2.2 Recommended Test Equipment

2.2.1 Power Supplies

1. Power supply #1 (PS #1) capable of supplying 6 V at 3 A is required.

2. If not using a battery as the load, then power supply #2 (PS #2) capable of supplying up to 5 V at 4 A

is required to power the circuit shown in Figure 3.

2.2.2 Load #1 Between BAT and GND

Testing with an actual battery is the best way to verify operation in the system. If a battery is not available,

then a circuit similar to the one shown in Figure 3 can simulate a battery when connected to a power

supply.

2.2.3 Load #2 Between SYS and GND

Although not required, a resistive load capable of sinking up to 3 A can be used.

2.2.4 Meters

Four equivalent voltage meters (VM #) and two equivalent current meters (CM #) are required. The current

meters must be able to measure 4-A current.

2.2.5 Computer

A computer with at least one USB port and a USB cable is required. The bq2427x evaluation software

must be properly installed.

2.2.6 HPA172 Communication Kit (USB TO GPIO)

An HPA172 USB-to-I

C communication kit is required.
