Touchstone Semiconductor has expanded its Maxim Alternate-source Family to 15 Products

Touchstone Semiconductor has expanded its Maxim alternate-source family to 15 products with the addition of six new current-sense amplifiers. The company now offers eight current-sense amplifiers as part of its Maxim alternate-source family.

The new TSM9938H, TSM9938T, TSM9938W, TSM9634H, TSM9634T and TSM9634W current-sense amplifiers are pin-compatible, specification-identical and functionally identical to Maxim Integrated Products’ MAX9938H, MAX9938T, MAX9938W, MAX9634H, MAX9634T and MAX9634W. With the joining of the TSM9938F and TSM9634F, they form a complete product family. All versions of the TSM9938 and TSM9634 current-sense amplifiers are in stock now and available to ship immediately.

These alternate-source parts can be used in conjunction with Maxim’s products to ensure a constant supply of product so companies can build products and meet shipping deadlines.

The TSM9938 refer to low-power current-sense amplifiers that replace the MAX9938. They are guaranteed to operate from +1.6V to +28V, consume no more than 1μA supply current, have 500µV (max) input offset voltage and offer four fixed-gain options.

The TSM9634 is low-power current-sense amplifiers that replace the MAX9634. They are guaranteed to operate from +1.6V to +28V, consume no more than 1μA supply current, have 250µV (max) input offset voltage and offer four fixed-gain options.

Designed for portable/battery-powered systems, power management applications, over-current and fault detection, lamp monitoring, motor control, notebook computers, cell phones and other mobile and handheld personal communication devices, the TSM9938 and TSM9634 families are available in small-format, 5-pin SOT23-5 packaging.

TSM9938 pricing starts at $0.65 each per 1,000 part quantity. TSM9634 pricing starts at $0.71 each per 1,000 part quantity.

Touchstone’s other alternate-source products include TSM6025A/B, TSM9117/TSM9118, TSM9119/TSM9120, TSM917. TSM6025A/B are low-power, single-supply, precision +2.5V voltage reference ICs that are pin, specification, and functionally identical to the MAX6025A/B. TSM9117 and TSM9118 are low-power, single-supply comparators with voltage reference that are pin, specification, and functionally identical to the MAX9117 and MAX9118. They consume less than 600nA of supply current. TSM9119 and TSM9120 are low-power, single-supply comparator-only products that are pin specification, and functionally identical to the MAX9119 and MAX9120. They consume less than 400nA of supply current. TSM917 is a low-power, single-supply comparator that are pin, specification, and functionally identical to the MAX917 nanopower comparator, operates from a single +1.8V supply and consumes no more than 750nA of supply current.
