Inputs
The analog input (AIN) is used for PWM and analog inputs. The single-ended (DC) input test point is used
when a DC input is desired. See
PWM, Analog, and Single-Ended Inputs
, for more information.
2.6
Outputs
The DRV2700EVM has 4 referenced outputs (BST, OUT–, OUT+, and GND). They are output from a
terminal block to mitigate touching between two high voltage lines. See the
Output
section for additional
information.
2.7
BST/PVDD Disconnect
The BST jumper (JP12) is provided to allow disconnecting between PVDD and BST. This enables the
DRV2700EVM to be configured purely as a boost converter. See
Disconnecting BST/PVDD
, for additional
information.
2.8
TRIG Button
The DRV2700EVM has a built-in trigger button for user prototyping. If different modes of operation are
desired without using the GUI, the MSP430 can be programmed such that the trigger button can cycle
through different modes. Additionally, there are 3 test point pads that be can be used in a similar manner
through MSP430 firmware programming.
See
Figure 13
for a diagram of the input configuration.
