LT6119IMS-1#PBF

LINEAR TECHNOLOGY  LT6119IMS-1#PBF  电流检测放大器, 精准, 1个放大器, 60 nA, MSOP, 10 引脚, -40 °C, 85 °C

The is a complete high side Current Sense Device that incorporates a precision current sense amplifier, an integrated voltage reference and two latching comparators. The LT6119-1 has the comparators connected in opposing polarity. The comparator latch functionality can be enabled or disabled and the comparators can be configured to reset upon power-on. The input and the open-drain outputs of the comparators are independent from the current sense amplifier. The comparator trip points and amplifier gain are configured with external resistors. The overall propagation delay of the LT6119 is typically only 1.4µs, allowing for quick reaction to overcurrent and undercurrent conditions. The 1MHz bandwidth allows the LT6119 to be used for error detection in critical applications such as motor control. The high threshold accuracy of the comparators, combined with the ability to latch both comparators, ensures the LT6119 can capture high speed events.
