LTC2910 Octal Positive/Negative Voltage Monitor FEATURES DESCRIPTION 8 Low Voltage Adjustable Inputs (0.5V) The LTC 2910 is an octal input voltage monitor intended Guaranteed Threshold Accuracy: 1.5% for monitoring multiple voltages in a variety of applica- Input Glitch Rejection tions. Each input has a nominal 0.5V threshold, featuring Pin Selectable Input Polarity Allows 1.5% tight threshold accuracy over the entire operating Negative and OV Monitoring temperature range. Glitch ltering ensures reliable reset Buffered 1V Reference Output operation without false or noisy triggering. Adjustable Reset Timeout with Timeout Disable Polarity selection and a buffered reference allow monitor- 50A Quiescent Current ing up to two separate negative voltages. A three state Open Drain RST and RST Outputs input pin allows setting the polarity of two inputs without Guaranteed RST and RST for V 1V CC requiring any external components. Available in 16-Lead SSOP and 16-Lead The LTC2910 provides a precise, versatile, space-con- (5mm 3mm) DFN Packages scious, micropower solution for voltage monitoring. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
