PRINCIPLES OF OPERATION
voltage regulator
The TPIC43T01/02 receives an 8 to 28 V supply voltage at the VCC pin and generates an internal 5 V, VDD,
supply for the internal analog and digital logic. An external terminal for VDD is provided for a required external
1
F compensation capacitor. The regulator can also supply up to 10 mA current from the VDD pin to external
circuitry.
oscillators
internal oscillator
The device generates an internal 5.8 MHz clock to supply a frequency input to internal control blocks as
presented in Figure 4. No external components are required.

FG reference oscillator
The FG reference oscillator provides a clock to the FG frequency control section of the device. The oscillator
requires an external 5 to 10 MHz crystal to select the primary frequency. The user can alternatively input a 1
to 10 MHz signal from a signal generator to the OSC1 input to replace the external crystal. Two EEPROM bits
allow programming four different crystal oscillator divide-by values for controlling the FG reference frequency.
The FSEL pin provides an additional divide-by-2 for on-the-fly FG frequency (RPM) selection. Table 1 shows
the divide-by count and resulting FG reference frequency based on the two EEPROM bits (address 1, bits 0 –1)
and the FSEL pin input level.
