The LT6119 is a complete high side current sense device that incorporates a precision current sense amplifier, an integrated voltage reference and two latching comparators. Two versions of the LT6119 are available. The LT6119-1 has the comparators connected in opposing polarity and the LT6119-2 has the comparators connected in the same 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.

The LT6119 is fully specified for operation from –40°C to 125°C, making it suitable for industrial and automotive applications. The LT6119 is available in a small 10-lead MSOP.

Product Details

Demonstration circuit 2193A features the LT6119, a high side current sense amplifier with comparators and a 400mV reference.

The demo board circuit amplifies the voltage across an on-board current sense resistor, to provide a precision unipolar voltage output that is proportional to the sensed current. The board has two on-board comparators with latching outputs and an integrated 400mV reference that sets the threshold for the comparators. There are two versions of the board, A and B. The version determines the available comparator inputs. The DC2261A-A (LT6119-1) has an inverting and a noninverting comparator input available while the DC2261A-B (LT6119-2) has two inverting inputs available.
