The LT®6118 is a plete high side current sense device that incorporates a precision current sense amplifier, an integrated voltage reference and a latching parator. The parator latch functionality can be enabled or disabled and the parator can be configured to reset upon power-on. The input and the open-drain output of the parator are independent from the current sense amplifier. The parator trip point and amplifier gain are configured with external resistors. The overall propagation delay of the LT6118 is typically only 1.4µs, allowing for quick reaction to overcurrent conditions. The 1MHz bandwidth allows the LT6118 to be used for error detection in critical applications such as motor control. The high threshold accuracy of the parator, bined with the ability to latch the parator, ensures the LT6118 can capture high speed events. The LT6118 is fully specified for operation from
- 40°C to 125°C, making it suitable for industrial and automotive applications. The LT6118 is available in the small 8-lead MSOP and 8-lead DFN packages.
