Note: Some datasheets show pins 17, 18, and 19 as duplicates to simplify PCB routing. In practice, connect them together.

), the A68064 cuts down conduction losses significantly. It is widely deployed in industrial main distribution units to safeguard logic boards from over-current faults or power surges. 3. Microcontroller Port Expansion

Before diving into pinouts and timing diagrams, let’s highlight the core features that make the A68064 a go-to component for interface applications:

Widely used in motor drivers and Uninterruptible Power Supplies (UPS) for AC/DC regulation. Display Driving: In latch driver configurations, it is pivotal for LCD/LED drivers

Bolted to an external heatsink for passive or active cooling. Key Applications & Performance Insights 1. Brushed Motor Control (PWM Switching) Note: Some datasheets show pins 17, 18, and

The A68064 is used in a wide range of applications, including:

Connects the cathodes of the internal flyback diodes. This pin must be tied directly to the positive load supply voltage ( VLOADcap V sub cap L cap O cap A cap D end-sub ) to suppress inductive voltage spikes. It is widely deployed in industrial main distribution

High-performance N-Channel structured topology with an extremely low static drain-source or forward on-resistance (

Open-collector Darlington outputs that sink current to ground when activated.

When driving inductive loads—such as relays, solenoids, or DC motors—the magnetic field collapses instantly when the output turns off. This creates a massive inductive voltage spike ( ) that can easily destroy the output transistors.
