Maxim IC introduces the MAX16055 precision hex voltage microprocessor (μP) for circuit monitors up to six system-supply voltages and asserts a single reset when any one supply voltage drops below its preset threshold. The MAX16055 significantly reduces system size and component count while improving reliability compared to multiple ICs or discrete components.
The MAX16055 includes internally fixed threshold options for monitoring 3.3V, 3.0V, 2.5V, 1.8V, 1.5V, 1.2V, 1.1V, 1.0V, and 0.9V supplies with -5% or -10% tolerance. The MAX16055 is also available with one to five adjustable threshold inputs to monitor voltages down to 0.5V.
A single active-low, open-drain output asserts when any monitored input falls below its associated threshold.
Main features of the Max16055 are : Precision Factory-Set Reset Threshold Options ( 3.3V, 3.0V, 2.5V, 1.8V, 1.5V, 1.2V, 1.1V, 1.0V, and 0.9V ) , Adjustable Voltage Threshold Monitors Down to 0.5V with 1.5% Accuracy , Open-Drain RESET Output with 70μA Internal Pullup, Fixed 140ms (min) Reset Timeout Period , Manual Reset Input , Reset Valid for IN1 ≥ 1V or IN2 ≥ 1V , Tolerance Select (5%/10%) Input .
Maxim Ic introduces the MAX11810/MAX11811 low-power touch interface solutions which operate from a single 1.7V to 3.6V supply, and target power-sensitive applications such as handheld equipment. MAX11810/MAX11811 ICs include a 4-wire resistive touch-screen controller, a haptic motor controller plus driver, and an IR proximity-sensing system. The MAX11810/MAX11811 contain a 12-bit SAR ADC and a multiplexer to interface with a 4-wire resistive touch-screen panel. A digital serial interface provides communications.
The MAX11810/MAX11811 include an advanced state machine, which performs digital preprocessing of the touch-screen measurements, reducing bus loading and application-processor resource requirements.
