DATA SHEET MOS INTEGRATED CIRCUIT µPD168102 MONOLITHIC 6-CHANNEL H BRIDGE DRIVER DESCRIPTION The µPD168102 is a monolithic 6-channel H bridge driver IC consisting of a CMOS controller and a MOS output stage. Because it uses a MOS process, this driver IC consumes less current and loses less voltage at the output stage than conventional driver ICs that use bipolar transistors. In addition, the µPD168102 employs P-channel MOSFETs in its output stage, eliminating the need for an on-chip the charge pump circuit. Therefore, the current consumption during circuit operation can be significantly reduced. Of the six output channels, four channels are voltage drive type and two channels are current drive type (voltage drive is also possible). The current drive method of the µPD168102 is the output chopping method, which realizes lower power consumption drive than the conventional high-power-dissipation linear drive method. The µPD168102 is housed in a 48-pin WQFN to decrease the mounting area and height. The µPD168102 can simultaneously drive two stepper motors and two DC motors and is ideal for the motor driver of digital still cameras.

When VIsel is set to high level, if the voltage becomes higher than the reference voltage (external input) and the current becomes higher than the current set by the feedback resistor, the output can be forcibly chopped. When VIsel is set to low level, channels 5 and 6 function in the same way as channels 1 to 4. Standby function The µPD168102 realizes a standby function by combining the input signals. By setting all the control input signals of channels 1 to 6 to low level, a standby mode in which the current consumption of the internal circuit is suppressed is entered. Note that the output status is high impedance (output open). BRKsel pin function By using the logic of BRKsel, whether the function that prevents the motor power supply rising in the Hi-Z output status (input L, L) is enabled or disabled can be selected. Refer to the truth table below. BRKsel Truth Table BRKsel Function L Hi-Z status H Regenerates output current using an internal channel. An internal timer is incorporated, through which the regeneration period is set for approx. 1 ms, and then the Hi-Z status is entered.

For details of the recommended soldering conditions, refer to the document Semiconductor Device Mounting Technology Manual (C10535E). For soldering methods and conditions other than those recommended below, contact an NEC sales representative. Surface Mounting Type Soldering Conditions Soldering Method Infrared reflow Note Soldering Conditions Recommended Condition Symbol Package peak temperature: 260°C, Time: 60 seconds max. (at 220°C or higher), Count: Three times or less, Exposure limit: 3 daysNote (after that, prebake at 125°C for 10 hours), Flux: Rosin-based flux with low chlorine content (chlorine 0.2 Wt% or below) is recommended IR60-103-3 After opening the dry pack, store it at 25°C or less and 65% RH or less for the allowable storage period. Caution Do not use different soldering methods together (except for partial heating). 14 Data Sheet S15301EJ1V0DS µPD168102 NOTES FOR CMOS DEVICES 1 PRECAUTION AGAINST ESD FOR SEMICONDUCTORS Note: Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and ultimately degrade the device operation. Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor devices on it. 2 HANDLING OF UNUSED INPUT PINS FOR CMOS Note: No connection for CMOS device inputs can be cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected to V DD or GND with a resistor, if it is considered to have a possibility of being an output pin. All handling related to the unused pins must be judged device by device and related specifications governing the devices. 3 STATUS BEFORE INITIALIZATION OF MOS DEVICES Note: Power-on does not necessarily define initial status of MOS device. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the devices with reset function have not yet been initialized. Hence, power-on does not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function. Data Sheet S15301EJ1V0DS 15 µ3' • The information in this document is current as of February, 2002.
