1-1 Introduction This user ’ s guide describes the bq24010/2 (bqTINY ) evaluation module. The EVM provides a convenient method for evaluating the performance of a charge-management solution for portable applications using the bq24010/2 product family .
Background 1-2 1.1 Background The bqTINY series are highly integrated Li-Ion and Li-Pol linear charge management devices targeted at space limited portable applications.
2-1 T est Summary T est Summary This chapter shows the test setups used and the tests performed in evaluating the EVM. Setup : The bq24010/2 EVM board requires a 5-VDC, 1-A power source to provide input power and a single-cell Li-Ion or Li-Pol battery pack.
I/O and Jumper Connections 2-2 2.1 I/O and Jumper Connections Jack Connect T o: J1 – DC+ Power supply positive, preset to 5.0VDC, 1-A current limit. J1 – DC – Power supply ground J2 – BA T+ Po.
T est Procedure 2-3 T est Summary In place of a battery , a source meter that can sink current can easily be adjusted to test each mode. Another way to briefly see each mode on a scope is to connect a.
T est Procedure 2-4 2.2.1 Equipment 1) Power source: current-limited 5-V lab supply with its current limit set to 1.0 A ± 0.1 A 2) T wo Fluke 75, equivalent or better 3) Oscilloscope – TDS220 or better 4) Load test board (See Figure 2 – 1.) Figure 2 – 1.
T est Procedure 2-5 T est Summary 4) V erify that output voltage BA T+ settles between 3.2 V and 3.95 V . 5) V erify that the input current is between 0.69 A and 0.75 A. 6) Open switch SW3. 7) V erify that the input current is between 100 mA and 150 mA.
