3 Modifications
See the bq501210 data sheet ( SLUSCF5 ) when changing components:
• Use LED Mode – (Resistor R9) to change the behavior of the status LEDs D6, D7, and D8. The
standard value is 42.2 k
Ω
for control option 1, see the data sheet for additional settings.
• NTC – Connector JP3 provides the option for connecting a negative temperature coefficient (NTC)
sensor for thermal protection, see the data sheet for additional settings.
• FOD – R8 threshold and R49 FOD_Cal (see Section 6.2.2.7 )
• FOD_Ping – R47 and R48 (see Section 6.2.2.7 )
• PMOD – R16 threshold and disable (see Section 6.2.2.7 )
4 Connector and Test Point Descriptions
4.1 Input/Output Connections
The connection points are described in Section 4.1.1 through Section 4.1.9 .
4.1.1 J1 – V
IN
Input power 12 V to 19 V, return at J2. 15 V to 19 V recommended for full 15-W delivery.
4.1.2 J2 – GND
Return for input power, input at J1.
4.1.3 J3 – JTAG
Factory use only, not populated.
4.1.4 J4 – Serial Interface
I
2
C interface connection to communicate with the device. Used with bqTESLA TX Tuning Tool to monitor
behavior.
4.1.5 J5 – Micro-USB
Micro-USB input used for HVDCP testing.
4.1.6 JP1 – FOD / PMOD Enable
Shorting jumper must be installed to enable FOD and PMOD functions. See the data sheet for additional
details. Default - Shorted.
4.1.7 JP2 – LED Mode
External connection for LED MODE resistor, if R9 is removed. When shorted, the device disables the LED
and inhibits low-power mode. This is useful for troubleshooting. Default - Open.
4.1.8 JP3 – NTC
The connection point for the external temperature sensor. See the data sheet for more information.
Default - Open.
4.1.9 JP4 – Input Selection
Shunt selects 19-V input (J1) or micro-USB input (J5). Default position is J1 for 19-V input.
