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
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.
