LT6119-1/LT6119-2 Current Sense Amplifier, Reference and Comparators with POR Fea T Descrip T n Current Sense Amplifier The LT 6119 is a complete high side current sense device Fast Step Response: 500ns that incorporates a precision current sense amplifier, an Low Offset Voltage: 200V Maximum integrated voltage reference and two latching comparators. Low Gain Error: 0.2% Maximum Two versions of the LT6119 are available. The LT6119-1 n Internal 400mV Precision Reference has the comparators connected in opposing polarity and n Internal Latching Comparators the LT6119-2 has the comparators connected in the same Power-On Reset Capability polarity. The comparator latch functionality can be enabled Fast Response Time: 500ns or disabled and the comparators can be configured to reset Total Threshold Error: 1.25% Maximum upon power-on. The input and the open-drain outputs of Two Comparator Polarity Options the comparators are independent from the current sense n Wide Supply Range: 2.7V to 60V amplifier. The comparator trip points and amplifier gain n Supply Current: 550A are configured with external resistors. n Specified for 40C to 125C Temperature Range The overall propagation delay of the LT6119 is typically n Available in 10-Lead MSOP Package only 1.4s, allowing for quick reaction to overcurrent and undercurrent conditions. The 1MHz bandwidth allows the a T LT6119 to be used for error detection in critical applica- tions such as motor control. The high threshold accuracy n Overcurrent, Undercurrent and Fault Detection of the comparators, combined with the ability to latch n Current Shunt Measurement both comparators, ensures the LT6119 can capture high n Battery Monitoring speed events. n Motor Control n Automotive Monitoring and Control The LT6119 is fully specified for operation from 40C n Industrial Control to 125C, making it suitable for industrial and automo- tive applications.
