Asahi Kasei Microdevices/AKM AP1013AS

Overview

AP1013AS from Asahi Kasei Microdevices (AKM) is a single-channel H-bridge motor driver IC with integrated N-channel LDMOS high-side and low-side output stages, rated for 18V motor supply, 1.1A DC continuous output current at 25°C, and four operational modes (forward, reverse, brake, standby). It is used in compact motor control applications such as portable fans, small robotics actuators, and optical lens positioners.

For engineers reviewing the AP1013AS datasheet, AP1013AS pinout, AP1013AS application, or AP1013AS equivalent, key selection considerations include its 16-pin TSSOP package, 0.36Ω typical H-bridge on-resistance, under-voltage lockout at 2.2V, thermal shutdown at 175°C junction temperature, and compatibility with 2.7–5.5V logic supply.

Technical Context

The AP1013AS implements a fully integrated NMOS H-bridge topology with independent high-side and low-side LDMOS drivers, enabling bidirectional DC motor control without external FETs. Its internal charge pump supports high-side gate drive across the full 2.7–5.5V logic supply range.

Control logic accepts standard two-input phase-enable or PWM-input interface configurations, with built-in shoot-through prevention and automatic dead-time insertion. The device integrates analog monitoring circuits for undervoltage detection (2.2V threshold) and thermal protection (175°C trip, hysteresis not specified).

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous motor supply voltage for the AP1013AS?

The AP1013AS supports a maximum continuous motor supply voltage of 18V on the VM pin. This rating is validated across the full operating temperature range and accounts for transient spikes per the datasheet test conditions. Operation above 18V may cause permanent damage to the internal LDMOS output stages. Always ensure VM decoupling capacitance meets AKM's recommended layout guidelines to maintain stability at this upper limit.

Does the AP1013AS require external flyback diodes?

No, the AP1013AS does not require external flyback diodes. Its integrated NMOS H-bridge includes body diodes inherent to the LDMOS structure, which provide freewheeling paths during PWM switching and braking. These internal diodes are rated for the device's specified peak current (1.8A) and thermal limits. External diodes are unnecessary unless system-level EMI or voltage overshoot requirements mandate additional clamping.

How does the ISEN pin on the AP1013AS function?

The ISEN pin on the AP1013AS provides an analog voltage output proportional to the instantaneous motor current flowing through the H-bridge. While the exact scaling factor (mV/A) is not published in the provided source, it is intended for external monitoring or closed-loop current limiting. Designers must condition this signal with appropriate filtering and ADC interfacing; the AP1013AS itself does not perform current regulation internally.

What happens when the AP1013AS enters thermal shutdown?

When the AP1013AS junction temperature reaches approximately 175°C, its internal thermal shutdown circuit activates, turning off both high-side and low-side LDMOS outputs immediately. The device remains latched in this state until the junction cools below the hysteresis threshold (not specified in source), at which point normal operation resumes automatically. No external reset is required, and control inputs remain monitored during shutdown.

Can the AP1013AS operate from a 3.3V logic supply?

Yes, the AP1013AS fully supports 3.3V logic supply on the VCC pin. Its control supply range is specified as 2.7V to 5.5V, and all digital inputs (IN1, IN2, EN) are guaranteed to recognize 3.3V-compatible logic levels. The internal charge pump and gate drivers maintain proper high-side NMOS turn-on across this entire range, ensuring reliable H-bridge switching without external level-shifting circuitry.
