LT6109-1/LT6109-2 High Side Current Sense Amplifier with Reference and parators DESCRIPTION
The LT®6109 is a plete high side current sense device that incorporates a precision current sense amplifier, an integrated voltage reference and two parators. Two versions of the LT6109 are available. The LT6109-1 has the parators connected in opposing polarity and the LT6109-2 has the parators connected in the same polarity. In addition, the current sense amplifier and parator inputs and outputs are directly accessible. The amplifier gain and parator trip points are configured by external resistors. The open-drain parator outputs allows for easy interface to other system ponents. The overall propagation delay of the LT6109 is typically only 1.4µs, allowing for quick reaction to overcurrent and undercurrent conditions. The 1MHz bandwidth allows the LT6109 to be used for error detection in critical applications such as motor control. The high threshold accuracy of the parators, bined with the ability to latch both parators, ensures the LT6109 can capture high speed events. The LT6109 is fully specified for operation from
- 40°C to 125°C, making it suitable for industrial and automotive applications. The LT6109 is available in a small 10-lead MSOP .
