Touchstone adds six new analog ICs to alternate-source Maxim product family
The new current-sense amplifiers include the TSM9938H, TSM9938T and TSM9938W and the TSM9634H, TSM9634T and TSM9634W.
They are pin-compatible, specification-identical and functionally identical to Maxim Integrated Products’ MAX9938H, MAX9938T and MAX9938W and the MAX9634H, MAX9634T and MAX9634W. They join the TSM9938F and TSM9634F to form a complete product family.
All versions of the TSM9938 and TSM9634 current-sense amplifiers are in stock and available to ship immediately. Touchstone now offers 15 analog ICs as part of its Maxim alternate-source product family.
Touchstone’s 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.
Touchstone’s new analog product families offer the following features:
TSM9938 – low-power current-sense amplifiers that replaces the MAX9938.
They are guaranteed to operate from +1.6 V to +28 V, consume no more than 1 μA supply current, have 500 µV (max) input offset voltage and offer four fixed-gain options:
25V/V (TSM9938T)
50V/V (TSM9938F)
100V/V (TSM9938H)
200V/V (TSM9938W)
TSM9634 – low-power current-sense amplifiers that replaces the MAX9634.
They are guaranteed to operate from +1.6 V to +28 V, consume no more than 1 μA supply current, have 250 µV (max) input offset voltage and offer four fixed-gain options:
25V/V (TSM9634T)
50V/V (TSM9634F)
100V/V (TSM9634H)
200V/V (TSM9634W)
The TSM9938 and the TSM9634 are 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.
Availability and Pricing
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.
