• Output Voltage Range: 0V to Vcc
• Maximum Continuous Current: 1.5A per channel
• On-Resistance: 70mΩ (typical)
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The TPS2835DR has the following pin configuration:

```

---

| | --| EN1 OUT1 |-- Channel 1 --| IN1 GND | --| PG1 OUT2 | --| EN2 IN2 |-- Channel 2 --| PG2 GND | |___________| ```

Functional Features

• Independent control of each channel
• Fast turn-on and turn-off times
• Low voltage drop across the switch
• Fault detection and protection mechanisms

Advantages and Disadvantages

Advantages

• High-speed switching capability enables efficient power distribution in time-critical applications.
• Dual-channel design allows for simultaneous control of multiple power paths.
• Low on-resistance minimizes power loss and heat generation.
• Overcurrent and thermal protection ensure safe operation.

Disadvantages

• Limited maximum continuous current per channel (1.5A).
• Restricted input voltage range (2.7V to 5.5V).

Working Principles

The TPS2835DR operates by controlling the flow of current between its input and output pins. When enabled, it allows current to pass through from the input to the output. The device monitors the current and temperature conditions to provide protection against overcurrent and thermal issues.
