Page 13: Gpio Configuration
Getting to know the hardware The KIT33771TPLEVB has an integrated gateway communication link to an external local EEPROM. In high-voltage isolated applications, the MC33771’s I²C Communication Interface manages communication with the EEPROM. After a reset, the device automatically loads the EEPROM calibration parameters into the MC33771 registers. - Page 14 The KIT33771PTLEVB uses an optocoupler to detect a fault that is dependent on user defined internal or external faults. The Fault signal can be chained between EVBs and can be made available on the controller inputs. With two KIT33771TPLEVB boards, the fault is chained as shown below.
- Page 15 Some component values may be placed and adjusted for EMC purpose: C91 (default 22 pf), C92 (default 22 pF), R107, R108, C68, C69, and the pi filter made of R105, R106 and C93. By default, all other components (except C91 and C92) are not populated. KIT33771TPLEVB evaluation board, Rev. 2.0...

Page 18: Default Configuration
Configuring the hardware Isense connection A 0.1 Ω shunt resistor is available on the KIT33771TPLEVB for current measure during demonstrations. It is also possible to use an external shunt for current measure by disconnecting the embedded one. 5.2.1 Using the embedded 0.1 Ω shunt (default configuration) The current should be limited to ±500 mA to avoid any damage of the EVB. - Page 19 Configuration 1: measuring external loads and KIT33771TPLEVB currents Figure 15 illustrates the connections required to measure both external load currents and KIT33771TPLEVB loads. Connect the battery stack to the X1-1 to X1-4 pins (positive) and X1-33, X1-31 pins (negative). Connect one side of the external shunt to the X1-33 and X1-31 pins. Connect the other side to X1-34 and X1-32 pins.
