BLDC Driver

Gate Drivers

Figure 41 shows the PWM control of HBx in PWM (HBx_PWM_EN = 1): Turn-off of the active MOSFET (high-side

MOSFET in this case) followed by the activation of the FW MOSFET low-side MOSFET in this case) with PWM_NB

= 1, AGC[1:0] = 01B or 10B, POCHGDIS = 0 (post-charge enabled).

This control scheme is applicable for the following cases:

1. EN_GEN_CHECK = 0 (detection of FW/Active MOSFET disabled); HBxMODE[1:0] = 10B (HS MOSFET is

considered as active MOSFET by default).

2. EN_GEN_CHECK = 1 (detection of active / FW MOSFET enabled); HS MOSFET detected as active MOSFET;

HBxMODE[1:0] = 01B or 10B.

Note:

If the synchronized LS PWM rising edge occurs before the end of tHBxCCP active, then the device

prevents an activation of the LS MOSFET until tHBxCCP active elapses. In other words, the LS PWM

rising edge is ignored until the end of tHBxCCP active.
