The LT®6119 is a plete high side current sense device that incorporates a precision current sense amplifier, an integrated voltage reference and two latching parators. Two versions of the LT6119 are available. The LT6119-1 has the parators connected in opposing polarity and the LT6119-2 has the parators connected in the same polarity. The parator latch functionality can be enabled or disabled and the parators can be configured to reset upon power-on. The input and the open-drain outputs of the parators are independent from the current sense amplifier. The parator 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 parators, bined with the ability to latch both parators, ensures...
