uPD16818 Overview
The µPD16818 is a monolithic dual H bridge driver IC which uses N-channel power MOS FETs in its output stage. By employing the power MOS FETs for the output stage, this driver circuit has a substantially improved saturation voltage and power consumption as pared with conventional driver circuits that use bipolar transistors. In addition, the drive current can be adjusted by an external resistor in power-saving mode.
uPD16818 Key Features
- patible with 3V-/5V- supply voltage
- Pin patible with µPD16803
- Low ON resistance (sum of ON resistors of top and bottom MOS FETs)
- Low current consumption: IDD = 0.4 mA TYP. (VDD = 2.7 V to 3.6 V)
- Stop mode function that turns OFF all output MOS FETs
- Drive current can be set in power-saving mode (set by external resistor)
- pact surface mount package
