|2ch H-Bridge Small Motor Driver|
Motor Drive Voltage: 2 to 9V, Control Voltage: 2.7 to 5.5V, 1.1A
|Interchangeable lens for DSLRs, (digital single-lens reflex), high-end compact cameras, small stepping motors, home security cameras, communication robots|
To solve the problem of unwanted sound from a zooming operation within a video recording, Asahi Kasei Microdevices Corporation, (AKM), has developed and released a 9V 2ch H-bridge motor driver. The new AP1019AEN is quieter than competitive products by improving linearity during PWM operation with faster switching. Thus, rotation of the compact stepping motor becomes smoother with less noise. The AP1019AEN is ideal for applications such as a digital single-lens reflex/mirrorless cameras equipped with a lens that adjusts the zoom and aperture while shooting video, a home security camera that can pan, tilt, and zoom while talking, or a communication robot with a driven joint.
Drive frequency ranges to 1 MHz with the increase of switching speed, improvements include high linearity during PWM control, and reduced unevenness from rotation. Therefore, smooth rotation can be achieved even with higher motor rotation speed, but with less motor driving sound.
Built-in functions include Thermal Shutdown, (TSD), shoot-through current prevention, and Undervoltage Lockout (UVLO).
The AP1019AEN is housed in a 16-pin WLCSP, (1.96 × 1.96mm), package.
