Table 32. Register 0xFE06—Flag Reenable Delay, VDD_OV, and FLAGIN Configuration
Bits Bit Name R/W Description
These bits specify the global delay from when a flag is cleared to the soft start process.
Bit 7 Bit 6 Typical Delay Time
0 0 250 ms
0 1 500 ms
1 0 1 sec
[7:6] Flag reenable delay R/W
1 1 2 sec
5 VDD_OV flag ignore R/W This bit enables or disables the VDD_OV flag.
0 = VDD_OV flag enabled. When there is a VDD overvoltage condition, the flag is set and the
part shuts down. When the flag is cleared, the part restarts.
1 = VDD_OV flag is always cleared.
4
VDD_OV flag
debounce
R/W This bit sets the debounce time for the VDD_OV flag.
0 = 500 µs debounce time.
1 = 2 µs debounce time.
[3:2] FLAGIN action R/W These bits specify the action to take when the FLAGIN flag is set.
Bit 3 Bit 2 FLAGIN Action
0 0 None
0 1 Disable PWM outputs in Channel A
1 0 Disable PWM outputs in Channel B
1 1 Disable all PWM outputs (Channel A, Channel B, and Channel C)
R/W These bits specify the action to take after the FLAGIN flag is cleared.
Bit 1 Bit 0 Action After FLAGIN Is Cleared
0 0
After the reenable delay time, the PWM outputs are reenabled using the soft
start process
0 1 The PWM outputs are reenabled immediately without a soft start
1 0 A PSON signal is needed to reenable the PWM outputs
[1:0]
Action after FLAGIN
is cleared
1 1 A PSON signal is needed to reenable the PWM outputs
Register 0xFE07 selects flags to be blanked during soft start. When a flag is blanked, the flag is set but no action takes place. During the soft
start of any channel, the following flags are always blanked: FLAGIN, OTP1, OTP2, and ACSNS. During the soft start of Channel A, these
flags are also blanked: REVERSE_A and UVP_A. During the soft start of Channel B, these flags are also blanked: REVERSE_B and UVP_B.
Table 33. Register 0xFE07—Flag Blanking During Soft Start
Bits Bit Name R/W Description
7 Reserved R/W Reserved.
6 CS_OCP blanking R/W 0 = blank CS_OCP flag during Channel C soft start.
1 = do not blank CS_OCP flag.
5 OVP_B blanking R/W 0 = blank OVP_B flag during Channel B soft start.
1 = do not blank OVP_B flag.
4 OVP_A blanking R/W 0 = blank OVP_A flag during Channel A soft start.
1 = do not blank OVP_A flag.
3 CS2_B_OCP blanking R/W 0 = blank CS2_B_OCP flag during Channel B soft start.
1 = do not blank CS2_B_OCP flag.
2 CS2_A_OCP blanking R/W 0 = blank CS2_A_OCP flag during Channel A soft start.
1 = do not blank CS2_A_OCP flag.
1 CS1_B_OCP blanking R/W 0 = blank CS1_B_OCP flag during Channel B soft start.
1 = do not blank CS1_B_OCP flag.
0 CS1_A_OCP blanking R/W 0 = blank CS1_A_OCP flag during Channel A soft start.
1 = do not blank CS1_A_OCP flag.
