2.5 Jumper Information

Header J17:

  • VSEL-PD: VOUT = 3.3V with L+_24V as the LDO input supply.
  • VSEL-PU: VOUT = 5V with L+_24V as the LDO input supply.
  • No shunt jumper: VOUT = 3.3V with V5IN as the LDO input supply.

Header J13:

  • V5IN-5V: connects the board's 5V rail to the TIOL221 V5IN pin.
  • No shunt jumper: isolates the TIOL221 V5IN pin.

Header J5:

  • 5V-5V_EXT: connects the 5V rail of the board to the external 5V supply header J7 and TP20.
  • 5V-5V_LP: connects the 5V rail of the board to the 5V_LP rail of the board if connected to a TI LaunchPad.

Header J9:

  • SPI_PIN-GND: configures the TIOL221 to operate in pin-mode.
  • No shunt jumper: configures the TIOL221 to operate in SPI mode.

Header J15:

  • CS_PP-PD: The CQ and DO driver operates in either PNP or NPN mode if SPI/PIN is low.
  • CS_PP-PU: The CQ and DO driver operate in Push-Pull mode if SPI/PIN is low.
  • No shunt jumper and SPI/PIN is High: The CS/PP pin operates as the SPI chip select and CQ and DO driver modes selected via SPI.

Header J16:

  • SDI_NPN-PD: the CQ and DO driver operates in PNP mode if SPI/PIN is low and CS/PP is low.
  • SDI_NPN-PU: the CQ and DO driver operates in NPN mode if SPI/PIN is low and CS/PP is high.
  • No shunt jumper and SPI/PIN is high; the SDI/NPN pin operates as the SPI serial data input and CQ and DO driver modes selected via SPI.

L H X Push-Pull
H X X CQ & DO driver mode selected via SPI

Header J3:

  • CQ_EN-GND: the CQ driver is disabled if SPI/PIN is Low.
  • No shunt jumper and SPI/PIN is low; the CQ driver is enabled to transmit data supplied to the CQ_TX pin of the board.

Header J6:

  • DO_EN-GND: the DO driver is disabled if SPI/PIN is low.
  • No shunt jumper and SPI/PIN is low; the DO driver is enabled to transmit data supplied to the DO_TX pin of the board.

Header J12:

  • Shunt jumper on pins 1 and 2 next to LED D8: connects LED D8 to the SDO/NFLT2 pin when the device is used in pin-mode and SPI/PIN is low to indicate faults with the DO channel.
  • No shunt jumper on pins 1 and 2 and SPI/PIN is high: the SDO/NFLT2 pin operates as the SPI Serial Data Output.
  • Shunt jumper on pins 3 and 4 next to LED D2: connects LED D2 to the INT/NFLT1 pin when the device is used in pin-mode and SPI/PIN is low to indicate faults with the CQ channel.
  • No shunt jumper on pins 3 and 4 and SPI/PIN is high: the INT/NFLT1 pin operates as the interrupt output.
  • Shunt jumper on pins 5 and 6 next to LED D1: connects LED D1 to the RESET pin to indicate UV or VOUT.
  • No shunt jumper on pins 5 and 6: LED D1 is isolated from the RESET pin.

Header J4:

  • DO_ILIM_ADJ-GND: connects the ILIM_ADJ2 pin directly to GND (RSET = 0Ω).
  • DO_ILIM_ADJ-FIXED: connects the ILIM_ADJ2 pin to GND through a fixed resistor R3 (RSET = 25kΩ).
  • DO_ILIM_ADJ-VAR: connects the ILIM_ADJ2 pin to GND through a variable resistance potentiometer R4 (RSET = 0Ω to 100kΩ).
  • No shunt jumper: isolates the ILIM_ADJ2 pin (RSET = OPEN).

Header J8:

  • CQ_ILIM_ADJ-GND: connects the ILIM_ADJ1 pin directly to GND (RSET = 0Ω).
  • CQ_ILIM_ADJ-FIXED: connects the ILIM_ADJ1 pin to GND through a fixed resistor R7 (RSET = 25kΩ).
  • CQ_ILIM_ADJ-VAR: connects the ILIM_ADJ1 pin to GND through a variable resistance potentiometer R8 (RSET = 0Ω to 100kΩ).
  • No shunt jumper: isolates the ILIM_ADJ1 pin (RSET = OPEN).
