Semtech Corp. unveiled two new sub-1 V mixed-signal LED and motor timer-controllers, the SX8120 and SX8121 for consumer home and office appliance applications.
The two devices operate intrinsically at 0.9 V to control a DC motor or other continuous low-voltage element and drive a high-brightness LED directly from a single battery.
Because they operate inherently at 0.9 V, these devices do not require an external boost converter and inductor, saving board space, cost and weight.
Key Features:
The devices can be used in a range of sub-1 V small consumer home and office appliances applications, such as electric toothbrushes, shavers, automatic perfume dispensers, toys, LED pointers and LED torches.
Availability: The SX8120 and SX8121 are available now.
Pricing: $0.36 each in 2,500-piece lots.

Because they operate inherently at 0.9 V, these devices do not require an external boost converter and inductor, saving board space, cost and weight.
Key Features:
- Single-cell operation: AA or AAA alkaline, NiMH or NiCd battery
- Battery safe operation with 0.6 V I/O control
- 0.9 V to 2 V operation over the full industrial temperature range (-40 to +85°C)
- 1-button operation with 15 or 30 sec timeout (SX8120) and 10 min or no timeout (SX8121)
- DC motor control and boost control for high-brightness white or green LEDs
- No external boost converter and inductor required
- No software development needed
- Packaging: SOIC 8-pin, lead-free, halogen-free, fully RoHS and WEEE compliant
The devices can be used in a range of sub-1 V small consumer home and office appliances applications, such as electric toothbrushes, shavers, automatic perfume dispensers, toys, LED pointers and LED torches.
Availability: The SX8120 and SX8121 are available now.

This product will surely be proven great for small consumer products and will also help reducing the sizes of it as the article says, but it will also find many new areas where it will get most suited.
The greatness is this has got ample amount charge usage as it works upto 0.9V

I am puzzled by the assertion 'no inductor' when the diagram shows one boosting the LED drive?
Useful little chap though, handy auto-power-off timer for battery test equipment...
