PIN FUNCTION DESCRIPTION
Go to: www.freescale.com
These are the power supply pins of the device. These pins are
directly connected with the lead frame of the package and are tied to
the drain of the switching MOSFET. These pins can be directly
connected to the battery voltage. In addition to their supply functions,
these pins participate to the thermal behaviour of the device in
conducting the heat from the switching MOSFET to the printed circuit
board.
terminals. They are directly connected to the source of the power
MOSFET. The Rdson is 35mΩ max per output at 25°C. Its value
increases up to 50mΩ at 150°C junction temperature.
These are the device input pins, which directly control their
associated output. The thresholds are CMOS compatible. When the
input is in low state, the associated output MOSFET is off. When
input is high, the MOSFET is turned on and the load is activated.
When both inputs are low, the device is in standby mode and its
supply current is less than 1mA for V
These pins are the channel 1 and 2 status. Their internal structure is
an open drain with an internal clamp at 6V. An external pull up
connected to the 5V is needed. When the device is in normal
condition the status is high. If open load or overtemperature occurs
on one channel, the associated output status will be pulled low. See
Functional Truth Table.
