Definitions

  • FIG. 1 is a block diagram of a half-bridge motor driver according to an embodiment of the present invention.
  • VMs are respectively input to the comparators U8 and U9, and are connected to the gate terminals of the NMOS transistors M2 of the comparators.
  • OUT1 and OUT2 are input to the comparators U8 and U9, respectively, where OUT1 and OUT2 are connected to the gate terminal of the NMOS transistor M3 in each comparator.
  • the source terminal of M2 is connected to the drain terminal of the NMOS transistor M1 for supplying a constant current.
  • the source terminal of M3 is connected to the drain terminal of M1, which is configured to supply a constant current through an offset and hysteresis regulating resistors R1 and R2.
  • the resistor R2 is connected to an NMOS switch M7 that controls hysteresis.
  • the PMOS M4 and M5 act as active loads to determine the gain of the comparator and finally connect to the drain terminal of the NMOS M9 which supplies constant current through the PMOS M6.
