• Low quiescent current: The device features a low quiescent current, enabling power savings during standby or idle modes.
• Overcurrent protection: The TPS22965DSGT incorporates overcurrent protection to safeguard the connected electronic components from damage.

Package and Quantity

The TPS22965DSGT is available in a small form factor package, such as a 6-pin WSON (Wafer-level Chip Scale Package). It is typically sold in reels containing a specified quantity, usually 2500 units per reel.

Specifications

• Input voltage range: 2.5V to 5.5V
• Maximum continuous current: 2A
• On-resistance: 30mΩ (typical)
• Quiescent current: 1µA (typical)
• Operating temperature range: -40°C to 85°C

Pin Configuration

The TPS22965DSGT has six pins arranged as follows:

```

---

| | --| VBAT | --| GND | --| EN | --| IN | --| OUT | |___________| ```

• VBAT: Power supply input pin
• GND: Ground reference pin
• EN: Enable pin for controlling the power switch
• IN: Input pin for the power source
• OUT: Output pin for supplying power to the load

Functional Features

1. Power Switch Control: The TPS22965DSGT provides an enable pin (EN) that allows users to control the power switch, enabling or disabling power flow as needed.
2. Overcurrent Protection: The device incorporates overcurrent protection, automatically limiting the current to prevent damage to the connected components.
3. Fast Switching Speed: With its fast switching speed, this PMIC ensures efficient power delivery and quick response times.
4. Low Quiescent Current: The TPS22965DSGT features a low quiescent current, minimizing power consumption during standby or idle modes.

Advantages and Disadvantages

Advantages

• Efficient power management
• Fast switching speed
• Overcurrent protection
• Small form factor package

Disadvantages

• Limited maximum continuous current (2A)

Working Principles

The TPS22965DSGT operates by controlling the power switch between the input (IN) and output (OUT) pins. When the enable pin (EN) is high, the power switch is turned on, allowing power to flow from the input to the output. Conversely, when the enable pin is low, the power switch is turned off, interrupting the power flow.

Application Field Plans

The TPS22965DSGT can be used in various portable electronic devices, including: - Smartphones - Tablets - Wearable devices - Portable gaming consoles - Digital cameras

Alternative Models

1. TPS22966DSGT: Similar to TPS22965DSGT but with a higher maximum continuous current of 3A.
2. TPS22967DSGT: Similar to TPS22965DSGT but with a lower on-resistance of 20mΩ.
3. TPS22968DSGT: Similar to TPS22965DSGT but with a higher input voltage range of 2.7V to 5.5V.

These alternative models provide options with different specifications to suit specific application requirements.

In conclusion, the TPS22965DSGT is a power management integrated circuit designed for efficient power management in portable electronic devices. With its low on-resistance, fast switching speed, and overcurrent protection, it offers reliable power delivery and protection. While it has a limited maximum continuous current, it provides an excellent solution for various portable electronic applications.
