AP1016AEN

Overview

The AP1016AEN is a half-bridge driver IC designed for general-purpose and stepper motor applications. It features four independent half-bridge outputs with a continuous output current of 1A per channel and a peak output current of 1.4A. The device operates on a supply voltage range of 2.7V to 5.5V, supporting load voltages from 2V to 9V. It utilizes power MOSFET technology with typical on-resistances of 270 milliohms for both low-side and high-side switches. The component is housed in a 16-QFN (3x3) package with an exposed pad, suitable for surface-mount installation.

Feature Summary

• Integrates four independent half-bridge drivers for multi-phase control
• Incorporates over-temperature and under-voltage lockout protection mechanisms
• Supports logic interface signals for direct microcontroller connection
• Utilizes power MOSFET technology for efficient inductive load driving

Applications

• Stepper motor control systems
• General-purpose inductive load switching
• Power MOSFET gate driving circuits

Procurement Notes

Verify the specific ordering suffix required for tape-and-reel or cut-tape packaging formats before procurement. Confirm that the component status is acceptable for the intended design lifecycle, as it may be marked as not recommended for new designs due to potential minimum order quantity restrictions. Ensure compatibility with standard surface-mount assembly processes given the QFN package type.

Selection Notes

Select this component when designing circuits requiring four isolated half-bridge channels within a compact footprint. It is appropriate for low-to-medium power applications where a 1A continuous current rating suffices. Consider the 2V to 9V load voltage window and the 2.7V to 5.5V logic supply requirement to ensure proper system voltage alignment. The wide operating temperature range supports industrial environments.

Part Context

The AP1016AEN belongs to the AP1016 series of motor drivers manufactured by Asahi Kasei Microdevices/AKM. This series focuses on integrated solutions for driving inductive loads using power MOSFETs. The device complements other offerings in the portfolio by providing a dedicated four-channel half-bridge configuration, distinct from full-bridge or dual-bridge variants found in related product lines.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify if alternative components from the same manufacturer offer identical pinouts and electrical characteristics if cross-referencing is necessary.
