Regulated LED current from each of 2 outputs is set by single reference resistor, outputs can be connected in parallel or left unused as required, and current matching in each string is achieved without ballast resistor. Dual control pins are available for both switch (on/off) and master control (on/off/dim up/dim down) signals.
Current Sensor IC comes in micro sized package.Allegro MicroSystems Inc. Worcester, MA 01615
Mar 11, 2013 Housed in 3 x 3 x 0.75 mm QFN package with internal resistance of 0.6 mΩ, Model ACS711 is designed for high and low side sensing applications up to 100 Vdc, with over 30 A continuous current. Factory programming provides for optimized accuracy in IC, with integrated fast response fault output. Model ACS711 is suited for motor and pump control in white goods, short circuit and overpower detection in audio applications, lighting, and general power supply monitoring.
Direction Detection Sensor IC uses 2 Hall-effect switches.Allegro MicroSystems Inc. Worcester, MA 01615
Feb 22, 2013 Providing digital output signals that indicate speed and direction of target rotation, Model A1233 is suited for ring magnet based, speed and direction systems located in harsh automotive and industrial environments. Dual-channel monolithic IC contains 2 independent Hall-effect bipolar switches that are located 1.63 mm apart and are photolithographically aligned to better than 1 µm. High-frequency chopper-stabilization technique cancels offsets in each channel, providing stable operation.
Programmable Linear IC delivers output redundancy.Allegro MicroSystems Inc. Worcester, MA 01615
Feb 08, 2013 Targeting automotive market, Model A1359 provides dual tracking output, where PWM output tracks analog output to within ±3% mismatch. Accuracy is optimized via programmability on analog output pin. Device features One-Time Programming, using non-volatile memory, to optimize quiescent output voltage and Duty Cycle for application or circuit. Available in TSSOP-08 surface mount package, IC is suited for electronic power steering, transmission component position, and brake/clutch cylinder position.
Constant-Current LED Driver is AEC-Q100 qualified.Allegro MicroSystems Inc. Worcester, MA 01615
Jan 28, 2013 Integrating high-side, N-channel MOSFET switch, Model A6213 provides constant-current output up to 3 A to drive high-power LEDs. Output voltage automatically adjusts to optimize constant-current supply to variety of LED array configurations including multiple LEDs in series. LED dimming is accomplished via direct logic input PWM signal. Housed in 8-pin narrow SOIC package, IC is suited for automotive map lights, DRL daytime running lights, fog lights, and underhood lamps.
Hall-Effect Switch features advanced programming algorithm.Allegro MicroSystems Inc. Worcester, MA 01615
Dec 19, 2012 Utilizing chopper-stabilization technique to eliminate offset inherent in single-element devices, Model A1128 is suitable for high-temperature applications in automotive/industrial markets. Wide range of programmability is available on magnetic operate point, BOP, while hysteresis remains fixed. Offered in 3-lead ultra-mini SIP for through-hole mounting, unipolar device also uses dynamic offset cancellation technique, with internal high-frequency clock, which minimizes residual offset voltage.
Inverter Power Module drives 3-phase motors.Allegro MicroSystems Inc. Worcester, MA 01615
Dec 04, 2012 Used for controlling 3-phase motor power inverter systems and variable speed control systems, SCM1240M series accepts 85–253 Vac and provides 10–30 A (continuous) output. IC, supplied in DIP, withstands up to 600 V (IGBT breakdown voltage) and consists of all necessary power elements – 6 IGBTs, 3 pre-drive ICs, and 6 freewheeling diodes – needed to configure main circuit of inverter as well as bootstrap circuit (3 bootstrap diodes and 3 boot resistors) as high-side drive power supply.
