10.1.1 Component Placement

  • Low-ESR and low-ESL capacitors must be connected close to the device between the VCC1 and GND1 pins and between the VCC2, VEE2 and GND2 pins to support high peak currents when turning on the external power transistor.
  • Place the VBST and VREF caps as close to the device as possible.
