Applications Information
The voltage across the current sense resistor (R
pin. If the voltage across R
timer activates.
A small ceramic bypass capacitor close to this pin is recommended to suppress
transients which occur when the load current is switched off.
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 1.17V. This pin can also be used for remote
shutdown control.
An external resistor divider from the output sets the output voltage at which the
PGD pin switches. The threshold at the pin is 1.17V. An internal 22 µA current
source provides hysteresis.
An external capacitor connected to this pin sets the insertion time delay and the
Fault Timeout Period. The capacitor also sets the restart timing of the LM25061-2.
An external resistor connected to this pin, in conjunction with the current sense
resistor (R
pass MOSFET.
An open drain output. This output is high when the voltages at the FB pin and at
the UVLO pin are above their thresholds.
Connect to the output rail (external MOSFET source). Internally used to determine
the MOSFET V
Connect to the external MOSFET’s gate. This pin's voltage is limited at 19.5V
above ground.
