The internal linear voltage regulator supplies the internal gate drivers with a typical voltage of 5 V and current up
to 50 mA. An external output capacitor with low ESR is required on pin IVCC for stability and buffering transient
load currents. During normal operation the external boost MOSFET switch will draw transient currents from the
linear regulator and its output capacitor. Proper sizing of the output capacitor must be considered to supply
sufficient peak current to the gate of the external MOSFET switch. Please refer to application section for
recommendations on sizing the output capacitor. An integrated power-on reset circuit monitors the linear regulator
output voltage and resets the device in case the output voltage falls below the power-on reset threshold. The
power-on reset helps protect the external switches from excessive power dissipation by ensuring the gate drive
voltage is sufficient to enhance the gate of an external logic level n-channel MOSFET.
IVCC stays at around 300 mV when Enable signal is off. No external circuit should be connected to IVCC
