It is designed to drive inductive loads such as relays, solenoids, dc motors, stepping motors, and other high-current or high-voltage loads in positive-supply applications. All inputs are TTL compatible. Each output (Y) is a complete totem- pole drive with a Darlington transistor sink and a psuedo-Darlington source. Each full-H driver is enabled separately. Outputs 1Y1 and 1Y2 are enabled by 1EN and outputs 2Y1 and 2Y2 are enabled by 2EN. When an EN input is high, the associated channels are active. When an EN input is low, the associated channels are off (i.e., in the high-impedance state). Each half of the device forms a full-H reversible driver suitable for solenoid or motor applications. The current in each full-H driver can be monitored by connecting a resistor between the sense output terminal 1E and ground and another resistor between sense output terminal 2E and ground.

All voltage values are with respect to the network ground terminal, unless otherwise noted. 2. The maximum current limitation at this terminal generally occurs at a voltage of lower magnitude than the voltage limit, Neither the maximum current nor the maximum voltage for this terminal should be exceeded. 3. Combined output current applies to each of the two full-H drivers individually. This current is the sum of the currents at outputs 1Y1 and 1Y2 for full-H driver 1 and the sum of the currents at outputs 2Y1 and 2Y2 for full-H driver 2. The full-H drivers may carry the rated combined current simultaneously. 4. For operation above 25C free-air temperature, derate linearly at the rate of 28.6 mW/C. For operation above 75C case temperature, derate linearly at the rate of 333 mW/C. Due to variations in individual device electrical characteristics and thermal resistance, the built-in thermal overload protection may be activated at power levels slightly above or below the rated dissipation.

Speed control is achieved with a TLC555 timer. This provides variable duty cycle pulses to the EN input of the TPICO298. In this configuration, the operating frequency is approximately 1.2 kHz. The duty cycle is adjustable from 10% to 90% to provide a wide range of motor speeds. The motor direction is determined by the logic level at the direction control input. The circuit may be enabled or disabled by the logic level at the EN input. A 5-V supply for the logic and timer circuit is provided by a TL431 short regulator. For circuit operation, refer to the function table.
