AP1014AEC

Overview

The AP1014AEC is a dual H-bridge motor driver IC designed for operating voltages up to 7.0V. It features four drive modes: forward, reverse, brake, and standby. The device integrates N-channel LDMOS FETs in the high-side and low-side output circuits, achieving a typical on-resistance of 0.35Ω at 25°C. It supports a control supply voltage range of 2.7V to 5.5V and a wide motor drive operating voltage from 2.0V to 7.0V. Maximum DC output current is 1.1A at 25°C and 0.8A at 85°C, with peak currents reaching 2.0A. Built-in protections include under-voltage detection below 2.2V and thermal shutdown at 175°C junction temperature.

Feature Summary

• Integrates dual H-bridge architecture with N-channel LDMOS FETs for compact design
• Supports forward, reverse, brake, and standby drive modes via SEL terminal logic
• Includes built-in under-voltage detection and thermal shutdown protection circuits

Applications

• Driving various small motors
• PWM drive applications requiring specific input logic configuration

Procurement Notes

Verify the exact package type and electrical specifications against the official Asahi Kasei Microsystems datasheet before integration. Confirm that the 7.0V maximum rating aligns with your system's power supply constraints. Ensure thermal management strategies account for the specified junction temperature limits during operation.

Selection Notes

Select this component when a compact WL-CSP package is required alongside integrated power stages. It is suitable for designs needing independent control of two DC motors or a single bipolar stepper motor within a 7.0V limit. Consider the 0.35Ω on-resistance for efficiency calculations and verify compatibility with the SEL terminal logic levels for PWM driving.

Part Context

The AP1014AEC belongs to the AP101x series of motor drivers from Asahi Kasei Microdevices/AKM. This series focuses on integrating control and power stages into small form factors like WL-CSP. It targets portable and space-constrained applications requiring reliable motor control without external discrete components.
