Safety power supply for motor drives reference design

Details

TopologieAbwärtswandler
Eingangsspannung4.2-60 V
Ausgang 13.3 V / 1.5 A

Beschreibung

This reference design implements a safe-power supply for powering up microcontrollers in an architecture featuring two MCUs. The design has several protection features including overvoltage protection and short circuit protection to prevent the MCUs from getting damaged. The DC/DCs, LMR36515 and LMR36015 convert the 5-V and 12-V rail into 3.3 V, which is monitored by the TPS3703 and TPS3702 voltage monitors respectively

Eigenschaften

  • Overvoltage, overcurrent, and short circuit protection of the 3.3-V rail for powering the MCU
  • Protection of the power supply input from an overvoltage of up to 60 V
  • Small form factor for space-critical applications
  • Synchronous buck DC/DC converter with integrated switch optimized for > 90% efficiency and compact design

Typische Anwendungen

  • Servo drive functional safety module
