... SC2602A at 500kHz, providing a choice for optimum compromise between efficiency, external component size, and cost. Two SC2602s can be used together to sequence power up of telecom systems. The power good of the first SC2602 connected to the enable of the second SC2602 makes this possible. Typical Application Circuit ...

... MOSFET connected to DH, hence lowering the output voltage. Under Voltage Lockout The under voltage lockout circuit of the SC2602 assures that the high-side MOSFET driver outputs remain in the off state whenever the supply voltage drops below set param- eters. Lockout occurs if V falls below 4 ...
