Constant current
chopping
H: High level, L: Low level, Z: High impedance
Constant current chopping is possible for channels 5 and 6.
When VIsel is set to high level, if the voltage becomes higher than the reference voltage (external input) and the
current becomes higher than the current set by the feedback resistor, the output can be forcibly chopped.
When VIsel is set to low level, channels 5 and 6 function in the same way as channels 1 to 4.
Standby function
The
μ
PD168102 realizes a standby function by combining the input signals.
By setting all the control input signals of channels 1 to 6 to low level, a standby mode in which the current
consumption of the internal circuit is suppressed is entered. Note that the output status is high impedance
(output open).
BRKsel pin function
By using the logic of BRKsel, whether the function that prevents the motor power supply rising in the Hi-Z output
status (input L, L) is enabled or disabled can be selected. Refer to the truth table below.
BRKsel Truth Table
BRKsel
Function
L
Hi-Z status
H
Regenerates output current using an internal channel. An internal timer is incorporated, through which the
regeneration period is set for approx. 1 ms, and then the Hi-Z status is entered.
