VERSION: 0x10=first version of the IC
Identical numbers mean full digital compatibility.
W
0x06
OTP_PROG
Bit
OTP_PROGRAM – OTP programming
Write access programs OTP memory (one bit at a time),
Read access refreshes read data from OTP after a write
2..0
OTPBIT
Selection of OTP bit to be programmed to the selected
byte location (n=0..7: programs bit n to a logic 1)
5..4
OTPBYTE
Set to 00
15..8
OTPMAGIC
Set to 0xbd to enable programming. A programming
time of minimum 10ms per bit is recommended (check
by reading OTP_READ).
R
0x07
OTP_READ
Bit
OTP_READ (Access to OTP memory result and update)
See table 5.1.1!
7..0
OTP0 byte 0 read data

FACTORY_
CONF
4..0
FCLKTRIM (Reset default: OTP)
0…31: Lowest to highest clock frequency. Check at
charge pump output. The frequency span is not
guaranteed, but it is tested, that tuning to 12MHz
internal clock is possible. The devices come preset to
12MHz clock frequency by OTP programming.
(Reset Default: OTP)

SHORT_CONF
3..0
S2VS_LEVEL:
Short to VS detector level for lowside FETs. Checks for
voltage drop in LS MOSFET and sense resistor.
1 (highest sensitivity) … 15 (lowest sensitivity)
(Reset Default: OTP 6 or 12)
11..8
S2G_LEVEL:
Short to GND detector level for highside FETs. Checks
for voltage drop on high side MOSFET
2 (highest sensitivity) … 15 (lowest sensitivity)
(Reset Default: OTP 6 or 12)
17..16
SHORTFILTER:
Spike filtering bandwidth for short detection
0 (lowest, 100ns), 1 (1µs), 2 (2µs) 3 (3µs)
Hint: A good PCB layout will allow using setting 0.
Increase value, if erroneous short detection occurs.
(Reset Default = %01)
20
shortdelay: Short detection delay
0=750ns: normal, 1=1500ns: high
The short detection delay shall cover the bridge
switching time. 0 will work for most applications.
(Reset Default = 0)
