Protection and standby mode
Soft-down sequence:
Protection mode:
Protection mode can be left by 3 ways:
1. Entering standby mode by setting control
2. Starting the soft start sequence by setting control
3. Decreasing the supply voltage below 8.1 V.
Standby mode:
Start the sequence by setting control bit SOFTST = 0
BDRV duty cycle decreases
HDRV duty cycle decreases.
Pins HDRV and BDRV are floating
Continuous blanking at pin CLBL is active
Pin HUNLOCK is floating
PLL1 and PLL2 are disabled
Register contents are kept in internal memory.
Set control bit STDBY = 1
Driver outputs are floating (same as protection mode)
Supply current is 9 mA
Only the I
Contents of all registers except the value of bit STDBY
and bit SOFTST are lost
See L2 of Fig.19 for continuation.
bit SOFTST = 0 and control bit STDBY = 1
bit SOFTST = 1 (bit STDBY = don’t care);
