MITSUMI Hybrid Driver Monolithic IC MM1285 Hybrid Driver Monolithic IC MM1285 Outline This IC collects various driver functions used in pagers and other portable communication devices in a single chip. Recently there have been requests for more compact pagers and portable telephones, and at the same time new functions and features are being added, leading to a strong demand for miniaturized and hybrid components. This IC meets these needs through adoption of a miniature package. The speaker driver incorporates functions for varying audio volume through data, a feature which can be used in novel applications. Features 1. 2. 3. 4. Configuration: Speaker driver,vibration motor driver, two LED drivers The speaker driver is capable of varying the audio volume in four steps via parallel data Power can be supplied by a single dry-cell battery Low 0.1µA consumption current in standby mode Package TSOP-16A (MM1285XV) Absolute Maximum Ratings Item Storage temperature Operating temperature Power supply voltage Operating power supply voltage OUT1~4 Voltage applied to output pin OUT5 Pd Symbol TSTG TOPR VCC max.
