APL3529A
Active
Ultra-Low On-Resistance, Power Load Switch With Soft Start
Features
General Description
The APL3529A/B is an ultra-low On-resistance, powerdistribution switch with external soft start control. The APL3529A/B can be enabled by other power systems. Pulling and holding the EN voltage below 0.4V or ENB above 0.8V will shuts off the output. The device integrates over-temperature protection. The over temperature protection function shuts down the Nchannel MOSFET power switch when the junction temperature rises beyond 160oC and will automatically turns on the power switch when the temperature drops by 40oC. The device is available in lead free TDFN2x2-8 package.
Features
- 7.8mΩ (Typical) On-resistance
- Low Quiescent Current : 30µA (max)
- Soft Start Time Programmable by External Capacitor
- Wide Input Voltage Range (VIN): 0.8V to 5.5V
- Supply Voltage Range (VDD): 3V to 5.5V
- Enable Control Function
- Output Discharge when Switch Disabled
- Over-Temperature Protection with Hysteresis
- Tiny small TDFN2x2-8 Package
- Lead Free and Green Devices Available (RoHS Compliant)
