TPS92682EVM Constant Current Two-channel Boost and Boost-to-Battery
Table 2. Test Points
Test Point
Description
Metal turrets
All metal turrets are grounds.
VBAT
The VBAT test point allows for voltage measurement of the external power supply applied to the evaluation
board.
VIN
The VIN test point allows for voltage measurement of the power applied to the boost and boost-to-battery
channels after the EMI filter.
VDD
The VDD test point allows for voltage measurement of the VDD output of the TPS92682-Q1.
LH
The LH test point allows for applying a voltage to the LH pin and placing the TPS92682-Q1 in Limp Home
mode
FLT1
The FLT1 test point can be used to monitor the fault occurrence of the channel-1. When a fault occurs, FLT1
voltage level goes low. Note that during power up, FLT1 is low (due to POR). The Fault pins can be reset by
setting bit-7 of the EN register 0x00.
FLT2
The FLT2 test point can be used to monitor the fault occurrence of the channel-2. When a fault occurs, FLT2
voltage level goes low. Note that during power up, FLT2 is low (due to POR). The Fault pins can be reset by
setting bit-7 of the EN register 0x00. The FLT2 test point can also be used for synchronizing of the
TPS92682-Q1 with an external clock.
EN
EN test point is connected to the EN-pin of the TPS92682-Q1 device
PWM1
PWM1 test point is connected to the PWM1-pin of the TPS92682-Q1 device
PWM2
PWM2 test point is connected to the PWM2-pin of the TPS92682-Q1 device
LED1+
The LED1+ test point allows for voltage measurement of the channel-1 (boost) LED positive output.
LED1-
The LED1- test point is connected to the channel-1 (boost) LED negative output. This test point is connected
to the EVM ground via a zero-
Ω
resistor
LED2+
The LED2+ test point is connected to the channel-2 (boost-to-battery) LED positive output.
LED2-
The LED2- test point is connected to the channel-2 (boost-to-battery) LED negative output.
