PRINCIPLES OF OPERATION
charge pump
An external charge pump capacitor (CP) is connected across the CP1 and CP2 pins. An external storage
capacitor (CS) with a typical value of 0.01
F is connected from VCP to VCC (see functional block diagram). The
charge pump output, VCP, powers the high-side gate drive circuitry for the pre-FET drivers. An internal CPUV
monitors the voltage between VCP and VCC and disables all outputs through a signal to the global shutdown
circuit until VCP – VCC ≥ 5 V. The VCP voltage level is internally regulated to VCC + 15 V (typical).
pre-FET drivers
The TPIC43T01/02 contains three pre-FET driver blocks, each with an upper and lower gate drive for driving
the gates of two external power NMOS FETs configured as a half H-power stage (see Figure 21). The
TPIC43T01/02 is designed to drive the TI TPIC1310 Power+ Array, but it is capable of driving discrete N-channel
FET devices as well. Each pre-FET gate output is capable of sourcing at least 60 mA peak current and sinking
at least 100 mA peak of current. The lower gate drive outputs provide VGS to the external FET from 14 to 20 V.
The upper gate drive outputs drive the external FET gate from VCP and provide VGS voltage protection (clamp
UGx pin with respect to Phx pin) to prevent the gate voltage from exceeding 19 V and damaging the external
FET in the event of a shorted-load or shorted-phase winding to ground.
