Applications Information
Solder to the ground plane to reduce thermal resistance
Connect to the output rail (external MOSFET source). Internally used to
determine the MOSFET V
voltage.
Connect to the external MOSFET's gate.
The voltage across the current sense resistor (R
this pin. If the voltage across R
is limited and the fault timer activates.
This pin is the input supply connection for the device.
An external resistor divider from the system input voltage sets the under-voltage
turn-on threshold. An internal 20 µA current source provides hysteresis. The
enable threshold at the pin is nominally 2.48V. This pin can also be used for
remote shutdown control.
An external resistor divider from the system input voltage sets the over-voltage
turn-off threshold. An internal 21 µA current source provides hysteresis. The
disable threshold at the pin is 2.46V.
Analog device ground. Connect to GND at the pin.
