RT9703

Preliminary

Note 1. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those

indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect device reliability.

Note 2. Devices are ESD sensitive. Handling precaution recommended. The human body model is a 100pF capacitor

discharged through a 1.5k

Ω resistor into input and output pins.

Note 3. The device is not guaranteed to function outside its operating conditions.

Note 4. The FLAG delay time is input voltage dependent, see “Typical Operating Characteristics” graph for further details.

Note 5. Current limit is determined by: ILIMIT = 180k/RSET, where RSET is in ohms.

Note 6. It is important to note that the maximum current limit value shall be set properly in accordance with its supply voltage

otherwise which it may result in the failure occurrence. See “Maximum Current Limit vs. Supply Voltage” graph

shown on the applications information section for further details.

Note 7. For input voltage lower than 5V, the threshold level will subject to ±0.6V deviation throughout the operating junction

temperature range. Refer to the “Typical Operating Characteristics” graph for further details.

Note 8. RDS(ON) is measured at constant junction temperature by using a 1ms current pulse.
