Maxim Integrated Products introduces the DS3655, a secure battery-backup controller and supervisor with temperature and voltage monitoring. This is the industry's only ultra-low-power single-chip device to integrate a battery-backup controller, system power monitor, CPU supervisor, elapsed-time counter, temperature sensor, and tamper-detection comparator inputs. The high integration and advanced security features of the DS3655 make it ideal for point-of-sale (POS) terminals, the payment card industry (PCI), software-defined radios (SDRs), and other equipment in which data protection and security is critical. |

MILPITAS, CA – February 26, 2008 – Linear Technology Corporation introduces the LTC2919, a versatile triple supervisor that monitors its own supply voltage and two adjustable inputs. Polarity selection and a buffered reference output allow the LTC2919 to monitor a combination of two positive or negative supplies for undervoltage (UV) and overvoltage (OV) conditions. The two inputs have a nominal 0.5V threshold and tight ±1.5% accuracy over the full temperature range. In addition to monitoring the two adjustable inputs for UV or OV, the LTC2919 monitors the supply voltage at 2.5V, 3.3V or 5V at a fixed -10% UV |
