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
1: All half bridge drivers become shut down upon
final short detection
(Reset Default = 1)
29
disable_S2G
0: Short to GND (HS) protection enabled
1: No short to GND protection
(Reset Default = 0)
30
disable_S2VS
0: Short to VS (LS) protection enabled
1: No short to VS protection
(Reset Default = 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)
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)
