AOZ1374DI ALPHA & OMEGA SEMICONDUCTOR ECPowerTM 23 V 36 mΩ Protection Switch Programmable
Current Limit and True Reverse Current Blocking General Description Features AOZ1374DI is a current-limiting protection switch targeting
applications that require comprehensive protections.
Both VIN and VOUT terminals are rated at 28 V absolute
maximum. There is a programable soft-start feature up to
10ms to limit the inrush current for highly capacitive loads.
The supply current reduces to 5 µ A in shutdown. It also has
Input Under-Voltage Lock Out (UVLO), Input Over-Voltage
Protection (OVP), and Thermal Shut Down Protection (TSD).
AOZ1374DI has True Reverse Current Blocking (TRCB)
protection to avoid undesired reverse-current from VOUT to
VIN. It also features an internal current-limiting circuit that
protects the supply from large load current. The current limit
threshold can be set externally with a resistor.
AOZ1374DI-01 will auto-restart when the fault conditions
are cleared.
AOZ1374DI-02 will latch the power switch off in case of a
fault condition and EN must be reset to restart the device.
AOZ1374DI is available in small 3 mm x 3 mm 10-pin DFN
package. • 28 V abs max voltage rating on VIN and VOUT pin
• Typical RON: 36 m Ω
• Programmable current limit
• True Reverse Current Blocking (TRCB) …
