NEW PRODUCT DPS1035 24V/3.5A 1-CH POWER SWITCH W/ REVERSE-VOLTAGE PROTECTION Description The DPS1035 is part of a family of power switches optimized for the USB Type-CTM and other hot-swap applications. Through the analog interface, exception status is reported and functions like voltage limiting and output voltage ramp-up rate can be programmed. This device is designed to operate between 4.5V and 24V. Its built-in fault-handling mechanism includes reverse voltage and current blocking, input over-voltage protection, and thermal shutdown. In addition, the ramp-up time of the output voltage can be adjusted to minimize in-rush current and to ensure system stability. Before any exception condition is notified via the low-active FAULTB signal, deglitch of 7ms is applied to prevent false triggering.

Enable. ‘0’ = device OFF; ‘1’ = device ON. This pin must not be left floating. No Connection. All NC pins must be left floating. Device Ground Voltage Regulator. A 0.1μF capacitor is recommended between this pin and ground. IN Port Discharge Control. ’1’ = port voltage to be discharged; ‘0’ = disabled. OUT Port Discharge Control. ’1’ = port voltage to be discharged; ‘0’ = disabled. Fault Status Indicator. An external pull-up resistor is required. This active-low pin shall be tied to GND when not used. Ramp-up Control. A capacitor between this pin and GND sets the ramp-up rate. Voltage Limit Setting. A resistor between this pin and GND sets the over-voltage limit of the IN port. Output Port. Common Source. The exposed pad of the V-QFN4040-17 package must not be connected to any signal.
