synchronous rectification mode (EEPROM address 0, bit 3, default = H for TPIC43T01, default = L for
TPIC43T02)
The TPIC43T01 is set up with synchronous rectification enabled. With synchronous rectification enabled
(EEPROM address 0, bit 3 = H), the complimentary LGx of the phase being pulse-width-modulated will turn ON
inversely to UGx during each PWM cycle. This provides a low resistance path through the low-side FET,
operating in inverse, for recirculating inductive current of the motor winding. This technique improves drive
efficiency over allowing the inductive energy to recirculate through the FET’s drain-body diode. Dead-time will
be controlled in each half-H between upper to lower and lower to upper transitions to prevent high current
conduction directly through the power FETs. During this dead-time, recirculation current, due to load inductance,
will occur in the lower FET body diode. After dead-time, the complimentary LGx will be turned on, thus reducing
power dissipation by using the lower FET in inverse to produce a lower voltage drop across
r
DS(ON)
than would
occur across V
F
of the FET drain-body diode (see Figure 11).

Figure 11. Synchronous Rectification/Coast Mode Operation
The TPIC43T02 is set up with synchronous rectification disabled. With synchronous rectification disabled
(EEPROM address 0, bit 3 = L), the complimentary LGx will stay low during the OFF time of UGx, and inductive
current will thus recirculate through the lower external FET drain-body diode for the duration of t
