1) Specification for BLDC Drive, 6 MOSFET switching with 25 KHz. Test condition: I_Gx = - 100 µA, ICHARGE = IDISCHARGE
= 31(max), IDISCHARGEDIV2_N = 1 and ICHARGEDIV2_N = 1.
2) Not subject to production test.
3) This resistance is connected through a diode between SHx and GHx to ground.
4) ICHARGE = IDISCHARGE = 3(min).
5) ICHARGE = IDISCHARGE = 31(max).
6) This time applies when Bit DRV_CP_CTRL_STS.bit.CP_EN is set
7) This time applies when Bit DRV_CP_CLK_CTRL.bit.CPCLK_EN is set
