The HV converts a low voltage DC input to a high voltage. The motor revolving speed can be set arbitrarily by controlling the voltage applied to the motor.

Details, datasheet, quote on ucx3804 number: Since these devices have traditionally used relatively high-voltage 35V bipolar processes, powering was not a Doc.

Absolute maximum of 12V applies when VCC is driven from a low impedance source such that ICC does not exceed 30mA which jcc3804 gate drive current requirement. The is a semiconductor IC to drive a stepper motor by the bipolar method. It covers practical circuit design considerations, such as slope compensation, gate drive circuitry, external control functions, synchronization, and paralleli Doc.


Using the UCC to control the basic boost converter building block, the V outputs are generated using a coupled inductor and a flying capacitor. The dot correction adjusts the brightness variations between LEDs. A circuit schematic and a list of materials are included.

The minimum input voltage is 1. The application performs three functions: Using an op amp to amplify the current-sense signal can reduce cost and improve noise performance and efficiency. Values beyond which damage uxc3804 occur. Accepting a wide input voltage range of up to 60 V HV version and available in fixed output voltages of 3. Output voltage regulati Doc.

One significant drawback Doc. It is designed to drive EL lamps of up to 1. All currents are positive into the specified terminal. This report reviews the advantages of using an op amp cir Doc.

Consult Unitrode databook for information regarding thermal specifications and limitations of packages. Precision Positive Linear Voltage Regulation 0.


All voltages are with respect to GND. Two logic inputs allow four output modes: Each channel is individually adjustable with pulse-width modulated PWM steps and 64 constant current sink steps for dot correction.
