PRINCIPLES OF OPERATION
voltage regulator
The TPIC43T01/02 receives an 8 to 28 V supply voltage at the V
CC
pin and generates an internal 5 V, V
DD,
supply for the internal analog and digital logic. An external terminal for V
DD
is provided for a required external
1
μ
F compensation capacitor. The regulator can also supply up to 10 mA current from the V
DD
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.
