Hybrid Driver Monolithic IC MM1285 MITSUMI 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 Symbol Ratings Units Storage temperature TSTG -40~+125 °C Operating temperature TOPR -10~+50 °C Power supply voltage VCC max. -0.3~+6 V Operating power supply voltage Vccop +1.0~+1.7 V OUT1~4 -0.3~+15 V OUT5 -0.3~+5 V -0.3~+5 V 300 mW Voltage applied to output pin Voltage applied to input pin Allowable loss Pd Hybrid Driver Monolithic IC MM1285 MITSUMI Pin Assignment 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 I/O Timing Chart LED1 Input Output LED2 Input Output Vibrator Input Output Speaker Input SW1 SW2 Output Application Circuits 1 VCC 9 O5 2 I1 10 O4 3 I2 11 GND 4 I3 12 O3 5 I4 13 O2 6 S1 14 O1 7 S2 15 KATHODE 8 I5 16 ANODE Hybrid Driver Monolithic IC MM1285 MITSUMI Electrical Characteristics (Except where noted otherwise, Ta=25°C, VCC=1.5V) Item Measurement conditions Standby current All input pins=0V - - 0.1 µA Consumption current A (O1 pin ON) I1=H, another pin=L 1.4 2.2 2.9 mA Consumption current B (O2 pin ON) I2=H, another pin=L 1.4 2.2 2.9 mA Consumption current C (O3 pin ON) I3=H, another pin=L 7.0 11.0 14.5 mA Consumption current D (O4 pin ON) I4=H, S1=H, S2=H, another pin=L 7.0 11.0 14.5 mA Consumption current E (O4 pin ON) I4=H, S1=H, S2=H, another pin=L 3.5 5.5 8.0 mA Consumption current F (O4 pin ON) I4=H, S1=H, S2=H, another pin=L 1.1 1.6 2.2 mA Consumption current G (O4 pin ON) I4=H, S1=H, S2=H, another pin=L 0.45 0.70 0.95 mA Input threshold All input pins 0.40 0.65 0.85 V Input resistance value Input current Min.
