Output pin for driving external NMOS or NPN
When driving an NPN, a resistor should be added for limiting base current.
Feedback pin of the built-in LDO (Internal Vref = 0.86V)
Voltage output pin of the built-in LDO
Drain output pin of the NMOS of the built-in low voltage detector
This pin will be internally pulled low when the voltage at LBI pin drops to
below 0.86V.
Input pin of the built-in low voltage detector
Trip point = 0.86V
Feedback input pin
Internal reference voltage for the error amplifier is 1.25V.
Input positive power pin of RT9262/A
Pin for switching
Chip enable
RT9262/A gets into shutdown mode when CE pin set to low.
