Product details
Overview
AP1016AEN from Asahi Kasei Microdevices is a dual-channel H-bridge motor driver IC designed for precise bidirectional control of stepper and voice coil motors. It integrates two independent H-bridges, charge pump circuitry, under-voltage lockout (UVDN) at 2.2 V nominal, thermal shutdown (TSD) at 175 °C, and delivers 0.7 A DC output current per channel with 0.54 Ω total RDS(ON) at 25 °C in a 16-pin QFN 3 mm × 3 mm package.
For engineers reviewing the AP1016AEN datasheet, AP1016AEN pinout, AP1016AEN application, or AP1016AEN equivalent, this device supports PWM-controlled motor motion up to 200 kHz, features integrated flow-through current protection, operates across -40 °C to +85 °C ambient, and requires no external high-side gate drivers due to its internal charge pump generating VG = VM + VC.
Technical Context
The AP1016AEN implements NMOS-based H-bridge topology on both high-side and low-side FETs per channel, enabled by an internal charge pump that generates gate drive voltage (VG) referenced to VM. Control logic accepts TTL/CMOS-compatible inputs (IN1A/IN1B/IN2A/IN2B) with 200 kΩ internal pull-down resistors and interprets them via truth table-defined motion states: forward, reverse, brake, and standby.
Protection is implemented through dual independent circuits: UVDN monitors VC supply and forces outputs to high-impedance if VC drops below 2.2 V (±0.3 V hysteresis), while TSD triggers at 175 °C junction temperature (±25 °C hysteresis), also forcing high-impedance outputs. Both protections retain state until recovery conditions are met.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Channels | 2 independent H-bridges for full bipolar motor control |
| Continuous Output Current | 0.7 A per channel at 85 °C ambient - defines maximum sustained torque delivery without thermal derating |
| Total RDS(ON) | 0.54 Ω (TOP+BOT) at 25 °C - determines conduction loss and self-heating under load |
| PWM Input Frequency | Up to 200 kHz - enables high-resolution microstepping and fast transient response |
| Supply Voltage Range | VC: 2.7–5.5 V; VM: 2.0–9.0 V - supports mixed-voltage system integration (e.g., 3.3 V logic + 5–9 V motor rail) |
| Protection Functions | Integrated UVDN (2.2 V threshold) and TSD (175 °C trigger) - eliminates need for external supervision circuitry |
| Package | 16-pin QFN, 3 mm × 3 mm, exposed thermal pad - enables compact PCB layout and efficient heat dissipation |
Pinout & Package
AP1016AEN uses a 16-pin QFN package (3 mm × 3 mm) with an exposed thermal pad (EP) requiring solder connection to PCB ground for thermal management. Pin 1 is marked by a dot; top-view pin numbering follows standard counter-clockwise orientation starting from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CL, CH | Charge pump capacitor terminals | Connect external 0.1 μF ceramic capacitors between CL–CH and CH–GND to stabilize internal charge pump operation |
| VM1, VM2 | Motor power supply inputs | Independent motor rails per channel; each must be decoupled with ≥1 μF capacitor near the pin |
| OUT1A/OUT1B, OUT2A/OUT2B | H-bridge output terminals | Drive motor windings directly; OUT1A/OUT1B form Channel 1; OUT2A/OUT2B form Channel 2 |
| GND1, GND2 | Power ground terminals | Dual ground pins reduce ground bounce; both must connect to low-impedance PCB ground plane |
| IN1A/IN1B, IN2A/IN2B | Logic input terminals | TTL/CMOS-compatible control signals with 200 kΩ internal pull-down; define motion state per channel |
| VC | Control circuit supply | Provides bias for logic, protection, and charge pump reference; monitored by UVDN circuit |
| VG | Charge pump output | Supplies gate drive voltage (≈ VM + VC) to high-side NMOS FETs; requires 0.1 μF bypass capacitor |
| EP | Exposed thermal pad | Mandatory ground connection for thermal performance; ≥4 thermal vias recommended beneath pad |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pump | Generates VG = VM + VC internally - eliminates external high-side gate driver ICs and reduces BOM count |
| Flow-through current protection | Prevents shoot-through during switching transitions - ensures safe commutation without external timing constraints |
| Thermal shutdown with hysteresis | Triggers at 175 °C with 30 °C hysteresis - prevents thermal runaway while allowing automatic recovery after cooling |
| Under-voltage lockout with hysteresis | Deactivates outputs below 2.2 V VC with 0.05 V hysteresis - avoids erratic behavior during brown-out conditions |
| Low quiescent current | 135–400 μA VC standby current - minimizes power draw in idle or sleep modes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual H-bridge motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TB6612FNG | Higher 1.2 A continuous current rating; separate VCC and VM supplies; no integrated charge pump (requires external bootstrap diode/capacitor) | Better suited for higher-torque 12 V stepper loads; lacks integrated UVDN/TSD hysteresis tuning | Select when >0.7 A current or 12 V motor operation is required; accept added external components for high-side drive |
| DRV8833 | Lower 1.5 A peak current; built-in current regulation; smaller 16-pin HTSSOP package; no charge pump (uses internal LDO for gate drive) | Optimized for low-voltage (≤5 V) battery-powered devices; includes current limiting but no thermal hysteresis spec | Select for cost-sensitive, low-power applications where current regulation is preferred over raw efficiency |
Compared with TB6612FNG and DRV8833, the AP1016AEN uniquely combines integrated charge pump, precise UVDN/TSD hysteresis, and 0.54 Ω RDS(ON) in a thermally optimized QFN - making it optimal for compact, thermally constrained 5–9 V stepper/VCM systems requiring deterministic fault handling.

FAQ
What is the maximum continuous output current supported by the AP1016AEN?
The AP1016AEN supports 0.7 A continuous output current per channel at 85 °C ambient temperature. This value is specified in the Absolute Maximum Ratings table and confirmed in Recommended Operating Conditions. At 25 °C, peak current capability reaches 1.4 A for ≤10 ms pulses. The AP1016AEN achieves this with 0.54 Ω total RDS(ON) at 25 °C, enabling efficient power delivery without external current-sense circuitry.
Does the AP1016AEN require external components for high-side gate driving?
No, the AP1016AEN does not require external components for high-side gate driving. It integrates a charge pump circuit that generates VG = VM + VC, providing sufficient gate voltage to fully enhance the NMOS high-side FETs. External 0.1 μF ceramic capacitors on CL and CH pins are required to stabilize the charge pump, but no bootstrap diodes, external LDOs, or gate driver ICs are needed - simplifying design and reducing bill-of-materials for the AP1016AEN.
How does the under-voltage lockout (UVDN) function in the AP1016AEN?
The AP1016AEN's UVDN circuit continuously monitors the VC supply voltage and disables all H-bridge outputs by forcing them into high-impedance state when VC falls below 2.2 V (typical), with ±0.3 V hysteresis. This prevents erratic switching or partial turn-on during brown-out conditions. Recovery occurs only after VC rises above 2.5 V. The AP1016AEN implements this entirely in hardware, ensuring deterministic behavior independent of MCU firmware status.
What thermal protection mechanisms are built into the AP1016AEN?
The AP1016AEN incorporates thermal shutdown (TSD) that activates at 175 °C junction temperature (typical), forcing all H-bridge outputs into high-impedance state. It includes 30 °C hysteresis, meaning the device remains disabled until junction temperature falls below 145 °C before resuming normal operation. This hardware-level protection is independent of external monitoring and is validated per AKM's MS1589-E-03 datasheet - a key reliability feature of the AP1016AEN.
Can the AP1016AEN drive both unipolar and bipolar stepper motors?
The AP1016AEN is designed for bipolar stepper motor control via its dual independent H-bridges, supporting full-step, half-step, and microstepping waveforms. It cannot directly drive unipolar steppers (which require center-tapped windings and single-ended drivers). For unipolar configurations, external rewiring or discrete transistor arrays would be needed - the AP1016AEN's native capability is strictly bipolar, as confirmed in its General Description and Truth Table sections of the AP1016AEN datasheet.
