SC4601 Overview
Key Features
- The use of high side P-channel MOSFETs eliminates the need for an external charge pump and simplifies the high side gate driver
- Non-overlap protection is provided for the gate drive signals to prevent shoot through of the MOSFET pair
- The voltage drop across the P-channel MOSFET during its conduction is sensed for lossless short circuit current limiting
- A low power sleep mode can be achieved by forcing the SYNC/SLEEP pin below 0.8V
- A synchronous mode of operation is activated as the SYNC/SLEEP pin is driven by an external clock
- The quiescent supply current in sleep mode is typically lower than 10µA
- A 2.4ms soft start is internally provided to prevent output voltage overshoot during start-up
