2.1 EVM Top View and Circuit Layout Partitions

GUID-20231114-SS0I-WSPN-JN5K-KPFS02KPQL3D-low.svg Figure 2-1 EVM Board Top View and Layout Partitions

Figure 4-16 shows the EVM board top view and circuit layout partitions. The EVM has the following parts:

• VLOW-Port: connected to Vbat rail

• VHIGH-Port: connected to Vbus rail

• Power Stage: TPS61289 power circuit

• Auxpower Part: this part provides 10 V, 5 V and -5 V to the control circuits

• Sampling and Compensation Part: sampling the battery remote voltage and charging/discharging current, generate the compensation signal

• DA Part: generate DA signals as the settings of the battery voltage and current

• USB2ANY Port: connection for USB2ANY
