Rainbow Electronics BA4910FP User Manual
High Voltage high side switch
BA4910FP
The BA4910FP is a high voltage high side switch
which has an output that can be turned ON/OFF by a
CTL pin. Circuit current of 1µA (Typ.) at standby is
perfect for power saving. Applications are various
including car stereos and printers.
Features
1) Maximum voltage of 50V PNP
2) Due to built-in output current control, IC is protected
from destruction caused by output short circuits
3) Built-in over current detection delay circuit
4) Surge resistant due to over voltage protection
circuit being built-in.
5) Built-in temperature protection circuit to protect IC
from thermal destruction
