Relay Driver IC RY-8023

Introduction

RY8023 is a bi-direction relay driver. The near zero standby current and a maximum of 800mA driving current make it suitable for applications such as electric energy meter and other application where low standby current and high driving current is needed .

Specification

1. Supply Voltage : 5 to 25V

2. Standby Current: 10nA

3. Input High Level    Threshold : 2V, compatible with most MCU output logic

4. Typical Driving Current : 300mA

Rds(on) ≈ 15ohms (Vdd=8V, PMOSFET+NMOSFET) Rds(on) ≈ 10ohms (Vdd=14V, PMOSFET+NMOSFET)

5. Peak Driving Current : 800mA (Vdd = 12V)

6.Operating Ambient Temperature: -40°C~80°C

7. Able to drive ≤ 90amps relay (Rdc = 16ohms) when Vdd = 9.5~14.5V
