Introduction www.ti.com 1.6 Control and Key Parameters Setting IC All 1.7 Jum Description per JP1 Default Factory Setting 1-2: FET GATE = BGATE: External PFET's gate tied to BGATE pin and therefore controlled by IC. 1-2 (FET GATE = 2-3: FET GATE = SYS: External PFET's gate tied to SYS and therefore disabled. BGATE) It is recommended that this jumper be changed only when the device is not enabled or in Hi-Z mode so that the PFET's gate is never left open.

Test Summary 2 www.ti.com Test Summary This procedure describes one test configuration of the HPA741 evaluation board for bench evaluation. 2.1 Definitions The following naming conventions are followed. VXXX : LOAD#: V(TPyyy): V(Jxx): V(TP(XXX)): V(XXX, YYY): I(JXX(YYY)): Jxx(BBB): JPx ON : JPx OFF: JPx (-YY-) Measure: → A,B Observe → A,B External voltage supply name (VIN, VUSB) External load name Voltage at internal test point TPyyy. For example, V(TP12) means the voltage at TP12.

Test Summary www.ti.com Figure 2. BAT Load (PR1010) Schematic 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 (VMx) and two equivalent current meters (CMx) are required. The current meters must be able to measure at least 3-A current. 2.3 Recommended Test Equipment Setup 1. For all power connections, use short, twisted-pair wires of appropriate gauge wire for the amount of the current. 2.

Test Summary www.ti.com 2.4.2 Charge Voltage and Current Regulation of USB 1. Ensure that the Section 2.3 steps are followed. 2. Move JP2 (CE1 or CE) = HI and JP6 = HI. 3. Connect the output of Power Supply number 1 (PS1) in series with current meter (multimeter) number 1 (CM1) to J4 and J8 or J6 (USB, GND). 4. Connect voltage meter 1 (VM1) across J4 or TP2 and J8 or TP5 (USB, GND). 5. With PS2 disabled, turn on PS1. 6. Measure: Measure on VM3 → V(J5/TP4(SYS),J9(GND)) = 4.

Printed-Circuit Board Layout Guideline 3 www.ti.com Printed-Circuit Board Layout Guideline 1. To obtain optimal performance, the power input capacitors, connected from the PMID input to PGND, must be placed as close as possible to the bq2416x. 2. Place 4.7-µF input capacitor as close to PMID pin and PGND pin as possible to make high-frequency current loop area as small as possible.
