• Manufacturer Part Number: MM908E621_08
• Description: Integrated Quad Half-bridge and Triple High Side with Embedded MCU and LIN for High End Mirror
• Manufacturer: FREESCALE [Freescale Semiconductor, Inc]

High Side Current Recopy
current recopy feature. This sense source is internally
connected to a shunt resistor. The drop voltage is amplified
and switched to the Analog Multiplexer.
Switchable HVDD Outputs
for driving external circuitry, which requires a 5V voltage. The
output is enabled with the PSON bit in the System Control
register, and can be switched on / off with the HVDD_ON bit
in the High Side Out register. Low or high voltage conditions
(LVIF / HVIF) will have no influence on this circuitry.
HVDD Over-temperature Protection
conditions.
HVDD Over-current Protection
case the current reaches the over-current limit, the output
current will be limited, and the HVDDOCF over-current flag in
the System Status register is set.
