LCD circuits often require a –10V voltage at 2 to 15 mA to bias a graphics-LCD-driver IC. You can usually accomplish this task with an external charge-pump IC, such as Maxim ’s ICL7660, but that ...

This Design Idea describes a circuit employing a small microcontroller-based sensor module with only three connections: 5V dc, an RS-232 transmit-data output, and ground. A dedicated single-voltage ...

The PIC16HV785 mixed signal microcontroller combines an 8bitmicrocontroller core with several on-chip analogue peripherals. Theseinclude a high speed, two-phase PWM circuit, ideal for ...

(See Fig. 1.) Microcontrollers and DSPs often incorporate such PWM conversion circuits as on-chip peripherals to drive electromechanical components like brakes and motors.

This microcontroller-based control circuit adjusts the speed of a small permanent-magnet DC motor to one of four speeds as selected by a pair of photosensors.

Such motors require higher-voltage PWM driver ICs to maintain high product reliability. Toshiba’s newly developed 600V TB67B000AHG driver IC is pin-compatible with the current 500V TB67B000HG ...

Those following the ProtoStack tutorials will be happy to hear that there is a new installment which explains Pulse Width Modulation. If you’ve never heard of PWM before, it’s a method … ...

Timing is everything and generating clocks based off a PWM signal is often useful. The same circuit generates up to eight independent clocks using a shift-register.

The device's PWM functionality allows smooth motor control: With an enhanced PWM frequency of up to 25 kHz, which is outside the human acoustic range, the DC motor control is carried out without ...

Power management IC suppliers, including those engaged mainly in the consumer electronics field, continue to see their supply remain constrained, according to industry sources.

Tight 8-inch fab capacities, rising costs, and other supply-side challenges that have challenged Taiwan-based power management (PWM) IC companies over the past year may persist for a while ...
