Maximal output current continuous 2A. Maximal
short term current 3A.
When not all channels are used it is recommended
to use gaps between channels (e.g. BO1, BO3,
BO5, BO7)
It is possible to invert channels logic in DriveConfig.
PWM is not available on BOUT1 to BOUT8.
Close corresponding jumper to avoid BW detection
of unused outputs BO1 to BO8.
BO 1/2 Fail is indicated in the case of BW on BO1
or BO2 (collected indication for 1-2, 3-4, 5-6, 7-8
output couples).
Reason of BOUT1 – BOUT8 disconnection (block) and error indication:
Short circuit (over 8 Amps) between BOUT 1-2; BOUT 3-4; BOUT 5-6; BOUT 7-8;
Short circuit (over 8 Amps) of any BOUT1-8 to BAT MINUS
Short circuit (over 8 Amps) of any BOUT1-8 to BAT PLUS
Overheat (over 150 °C on chip) and Undervoltage below 5.3V of chip supply.
Broken wire (just indication)
2.6.3 Binary outputs BO9 to BO16
There is one control signal for each binary channel. The load is closed or not depends if load is wired to plus or
minus of power supply (i.e. as Hi-side or Low-side switch). One of two switches on each Binary output is closed
and one opened in any operational case. Both switches are opened only when on-chip (e.g. overcurrent or
overheat) protection is activated.
Binary outputs BO9 to BO16 can be configured many different ways:
High-Side switches
Example:
BOUT9 and BOUT11 are
closed
BOUT10 and BOUT12 are opened
Configuration:
Property–Output type = BO
Property–Inverted = YES or NO
High-Side PWM
Configuration:
Property–Output type = PWM
Property–Output curve = … create in
Expert mode-User curves-Output curves
Or use linear curve
IMPORTANT: It is not recommended to use High-Side switches for activation of Emergency or
admission type of actuators (e.g. gas valves, fuel valves etc.).
