Notes
1. I_ref = ^V----R-r--^e-_I-^f-_r--_e⁽--^of--⁾-
2. Corresponds to an averaged variation of 7 mV/°C.
3. Including the V_CMSENSE amplifier input current.
4. Extended voltages are allowed if series resistors are used (see Fig.1).
5. The gain between the pre-driver output current and the IDRIVE current is typically; lower source = 35,
upper source = 50, lower sink = 75 and upper sink = 80.
6. Typical value for external FET such as PHN210.
7. I I_SPREF = _R--V---I-^r-_D-^e--_R-^f--⁽-_I-^oV---⁾-_E-
8. I I_source = 2 × ^V----R-r--^e-_I-^f-_r--_e⁽--^of--⁾-
9. Valid if the STOSC capacitance is in the nominal range of 150 to 700 pF.
10. t_BRAKEDELAY ≈ 2RC.
11. t_PORDELAY ≈ C_PORDELAY, with C_PORDELAY in µF.
12. Master clock (pin 58) must be running (1 cycle = T_ec) − t_IC = T_ecx (prescaler ratio).
