Introduction

The DIO7002 power distribution switch is intended for applications where precision current limiting is required or heavy capacitive loads and short circuits are encountered. The power switch rising and falling times are controlled to minimize current surges during turning on/off. The DIO7002 device limits the output current under a safe level by using a constant current mode when the output load exceeds the current limit threshold. The DIO7002 is available in the SOT23-5 packages. It is rated over the -40°C to ±85°C temperature range.

Features

• Input voltage: 2.7V to 5.5V

• Programmable current limit
• Enable polarity:
  • DIO7002A: Active high
  • DIO7002B: Active Low
• Over current protection, short circuit protection and over temperature protection
• Reverse blocking (no body diode)
• No reverse current when power ON or power OFF
• Compact SOT23-5 package minimizes the board space

Applications
