AP1511B

Specialized ICS Overview

The AP1511B is an IR-Cut Removable (ICR) driver IC manufactured by EVVO, designed to control infrared filter modules. It features a bidirectional H-bridge driver with internal resistance below 3 ohms and built-in protection diodes for feedback current and ESD suppression. The device operates on a single input line with one-shot functionality, supporting supply voltages from 2.5V to 5.5V. Key electrical parameters include a maximum steady-state standby current of 10µA, a typical saturation voltage of 0.73V at 300mA output, and a continuous output current rating of 500mA. It is housed in a SOT-23-6 package.

Specialized ICS Feature Summary

• One-shot operation controlled by a single input line
• Low standby current (<10µA) and low saturation voltage (0.73V@300mA)
• Built-in protection diodes for ICR feedback current and ESD

Specialized ICS Applications

• IR-Cut Removable (ICR) module driving
• Infrared filter switching in camera systems
• Light sensor-based automatic filter positioning circuits

Specialized ICS Procurement Notes

Verify the specific suffix 'B' against the manufacturer's official documentation to confirm if it denotes a distinct revision or packaging variant compared to the standard AP1511. Ensure the selected package matches the required SOT-23-6 form factor. Confirm RoHS compliance status directly with the supplier prior to procurement.

Specialized ICS Selection Notes

Select this component when designing circuits requiring precise control of ICR motor coils with minimal power consumption. The 2.5V to 5.5V operating range accommodates various logic levels. Consider the external capacitor value on the CE pin to determine the one-shot pulse width, accounting for temperature coefficients that reduce pulse duration as temperature rises.
