LT3689 - Micropower Step-Down Regulator Has On-Chip Power-On Reset & Watchdog Timer
Linear Technology has announced the LT3689, a 700mA, 36V input step-down switching regulator with a power-on reset and watchdog timer. Its Burst Mode operation keeps quiescent current under 85uA in no load standby conditions. The LT3689’s 3.6V to 36V input voltage range, with 60V transient ride through, makes it ideal for load dump and cold crank conditions commonly found in automotive applications.
Compact DMOS microstepping motor driver IC with built-in translator
The A4983 from Allegro MicroSystems Europe is a compact DMOS microstepping motor driver IC with built-in translator circuitry for easy operation. The new device combines an easy-to-use step and direction interface with a high output capability of up to 35 V and ±2 A and high-resolution microstepping control. It is designed for the PWM (pulse-width modulation) control of bipolar stepper motors in full-, half-, quarter-, eighth, and sixteenth-step...
Automotive grade relay driver IC
The new A2550 from Allegro MicroSystems Europe is an automotive grade relay driver IC which incorporates a 5 V voltage regulator, watchdog and reset circuitry, and three low-side DMOS relay driver outputs, providing robust performance over extended voltage and temperature ranges. The new device is designed to provide key functions in automotive relay-based applications where a microprocessor is used to implement complex system control and require...
Automotive-grade 3-phase motor-control ICs with built-in commutation logic
The new A3930 and A3931 from Allegro MicroSystems Europe are automotive-grade motor controller integrated circuits with built-in commutation logic to lessen the burden on the system microprocessor, simplifying system design and reducing cost. The new devices are ideally suited to the control of Hall-commutated 3-phase brushless DC motors driven by external N-Channel MOSFETs. If desired, the Hall sensor inputs can be driven directly by a micropro...
National Semiconductor Unveils SIMPLE SWITCHER Power Module Family
National Semiconductor introduced the first three products in its SIMPLE SWITCHER power module family. The LMZ-series of power modules provide an innovative, integrated solution that will save design time and provide ease-of-use to help system designers get their products to market faster. The power modules provide the efficiency of a synchronous switching regulator with the simplicity of a linear regulator, eliminating the external inductor and ...
Dual Voltage Supervisor Module In SOT-25 from TOREX
Combining the XC6108 with the XC6109 voltage supervisor in one small SOT-25 package, the XCM410 Series is the newest multi-chip module from Torex Semiconductor and features an ultra-low power consumption of only 1.7µA. The supervisor IC is ideal for those applications that need to monitor more than one voltage rail with a high degree of accuracy, such as microprocessor re-set circuits, memory battery back-up switch circuits and power failure det...
Voltage Supervisors from Torex with External Delay Function
The new XC6118 and XC6119 are 0.8µA low-power consumption supervisors that enable a delay time to be set up externally by connecting only a single capacitor to the ICs delay capacitor pin. In addition, the XC6118 also has a sense pin (VSEN) to monitor a separate power supply.
