Introducing the ET20170 by ETEK: Your Ultimate Power Protection Solution

2025/09/22

Elevate your power management systems with ETEK’s ET20170, a cutting-edge current-limiting power switch designed to safeguard sensitive electronics from voltage transients, overloads, and reverse-current damage. Perfect for high-reliability applications, this compact, feature-rich IC ensures robust protection and optimal performance.

Key Features:

1.Wide Input Range: 4.5V to 18V operation, supporting up to 5A continuous output current.

2.Ultra-Low Resistance: Just 31mΩ (typ) from input to output, minimizing power loss.

3.Smart Protection Suite:

Programmable current limit (0.73A to 5A) via external resistor.

Fast short-circuit response (<20µs) and thermal shutdown (155°C threshold).

Reverse-current blocking with external MOSFET driver (GATE pin).

4.Flexible Control: Adjustable soft-start timing via DV/DT capacitor for smooth power-up.

5.Energy Efficient: Ultra-low quiescent current (110µA typ) in active mode.

Ideal Applications:

USB Power Distribution/Protection (USB 3.1/PD compliant)

SSD/HDD Power Management

Wireless Modems & Server PCs

Industrial and Automotive Systems

Why Choose ET20170?
