Kim introduces a new system monitor and a precision high-voltage current sense amp:

• LM96080 - System hardware monitor with 2-wire interface
  • Local Temperature Sensing
  • 7 Positive Voltage Inputs with 10-bit Resolution
  • 2 Programmable Fan Speed Monitoring Inputs
  • 2.5 mV LSb and 2.56V Input Range
  • Chassis Intrusion Detector Input
  • WATCHDOG Comparison of All Monitored Values
  • Separate Input to Show Status in Interrupt Status Register of Additional External Temperature Sensors Such as the LM26/27, LM56/57, LM73, or LM75
  • I2C Serial Bus Interface Compatibility, Supports Standard Mode, 100 kbits/s, and Fast Mode, 400 kbits/s
  • Shutdown Mode to Minimize Power Consumption
  • Programmable ^RST_OUT/ ^OS Pin: ^RST_OUT Provides a Reset Output; ^OS Provides an Interrupt Output Activated by an Overtemperature Shutdown Event
  • Software and Pin Compatible with the LM80

• LMP8645/HV - Precision high voltage current sense amplifier
  • LMP8645: CMVR -2V to 42V
  • LMP8645HV: CMVR -2V to 76V
  • Supply voltage range: 2.7V to 12V
  • Gain configurable with a single resistor
  • Max variable gain accuracy (with external resistor) 2.0%
  • Transconductance: 200 μA/V
  • Low offset voltage: 1 mV
  • Input bias: 12 μA
  • PSRR: 90 dB
  • CMRR: 95 dB
  • Temperature range: −40°C to 125°C
  • 6-Pin TSOT Package
