MM908E625ACDWB/R2 Motorola, MM908E625ACDWB/R2 Datasheet - Page 34

• Manufacturer Part Number: MM908E625ACDWB/R2
• Description: Integrated Quad Half H-Bridge with Power Supply / Embedded MCU / and LIN Serial Communication
• Manufacturer: Motorola

Switchable VDD Outputs
can be used for driving external circuitry that requires a V
voltage. The output is enabled with bit PSON in the System
Control Register and can be switched on/off with bit HVDDON
in the Power Output Register. Low- or high-voltage conditions
(LVI/HVI) have no influence on this circuitry.
HVDD Overtemperature Protection
temperature reset is enabled.
HVDD Overcurrent Protection
event the overcurrent limit is or was reached, the output
automatically switches off and the HVDD overcurrent flag in the
System Status Register is set.
