Description / bit names
25..24 RETRY: Number of retries for short detection
0:
Half bridge disabled after first short detection
1..3: Half bridge re-enabled in next chopper cycles 1
time to 3 times. With retry, the short-counter is
decreased once each 256 chopper cycles per coil,
unless the upper limit has been reached.
(Reset Default = 3)
28 protect_parallel
0:
Only the detected half bridge driver becomes
shut down upon final short detection
All half bridge drivers become shut down upon
final short detection
1:
(Reset Default = 1)
29 disable_S2G
0:
1:
Short to GND (HS) protection enabled
No short to GND protection
(Reset Default = 0)
30 disable_S2VS
0:
1:
Short to VS (LS) protection enabled
No short to VS protection
(Reset Default = 0)
Bit
DRV_CONF
4..0 BBMCLKS:
0..15: Digital BBM time in clock cycles (typ. 42ns/CLK).
BBMCLKS is used in combination with singleline=1. It is
not applicable with individual LS and HS signals.
(Reset Default: OTP 1..4)
15:5 unused
17..16 OTSELECT:
Selection of over temperature level for bridge disable,
switch on after cool down to 120°C / OTPW level.
00: 150°C (default)
01: 143°C
10: 136°C
11: 120°C (not recommended, no hysteresis)
RW
0x0A
22 DRV_CONF
Hint: Adapt overtemperature threshold as required to
protect the MOSFETs or other components on the PCB.
(Reset Default = %00)
19..18 DRVSTRENGTH:
Selection of gate driver current. Adapts the gate driver
current to the gate charge of the external MOSFETs.
00: weak
01: weak+TC (medium above OTPW level)
10: medium
11: strong
Hint: Choose the lowest setting giving slopes <100ns.
(Reset Default = %10)
31:20 unused
