Touchstone intros first proprietary, low-power comparators for ultra-low power apps

MILPITAS, USA: Touchstone Semiconductor, a developer of high-performance analog integrated circuit solutions, announced the TS9001-1 and the TS9001-2, single-supply, low power analog comparators plus voltage reference ICs.

Both products are Touchstone Semiconductor’s first analog comparator products in its “NanoWatt Analog” high-performance analog integrated circuits portfolio.

The TS9001-1 and the TS9001-2 are electrical specification improvements over the MAX9117 and the MAX9118, respectively. Both TS9001s incorporate a +1.252V reference with a 1% initial accuracy, a 33 percent initial accuracy improvement over the MAX9117 or the MAX9118.

The TS9001-1 offers a robust push-pull output stage with increased output current drive while the TS9001-2 offers an open-drain output stage that can be used in mixed-voltage systems design. Both TS9001s are fully specified to operate from +1.6V to 5.5V supplies while consuming less than 0.65μA supply current.

The TS9001s are optimally designed for low-voltage, power-sensitive applications. These applications include: telemetry and remote systems, medical instrumentation, battery monitoring/management, as well as mobile and other hand-held communication devices.

Key specifications:
* Improved electrical performance over MAX9117-MAX9118.
* Guaranteed to operate down to +1.6V.
* Ultra-low supply current: 0.6μA.
* Internal +1.252V ±1% reference.
* Input voltage range extends 200mV outside-the-rails.
* No phase reversal for overdriven inputs.
* Output stage: push-pull (TS9001-1), open-drain (TS9001-2).
* Crowbar-current-free switching.
* Internal hysteresis for clean switching.

The TS9001-1 and the TS9001-2 are fully specified over the -40°C to +85°C industrial temperature range and are both offered in a space-saving 5-pin SC70 packages. TS9001 prices start at $0.95 each in 1000-piece quantities. Products are available from Future Electronics.
