description
The TPIC2101 is a monolithic integrated control circuit designed for direct current (dc) brush motor control that
generates a user-adjustable, fixed-frequency, variable duty cycle, pulse width modulated (PWM) signal
primarily to control rotor speed of a permanent magnet dc motor. The TPIC2101 can also be used to control
power to other loads such as solenoids and incandescent bulbs. This device drives the gate of an external, low
side NMOS power transistor to provide PWM controlled power to a motor or other loads. Inductive current from
motor or solenoid loads during PWM off-time is recirculated through an external diode.
The TPIC2101 accepts a 0% to 100% PWM signal (auto mode) or a 0 V to 2.2 V differential voltage (manual
mode), and internally engages the correct operating mode to accept the input type.
The device operates in a sleep state, a run state, or a fault state. In the sleep state the gate-drive (GD) terminal
is held low and the overall current draw is less than 200 µA. The normal operating mode of the device is in the
run state and is initiated by any speed command. When the device detects an overvoltage or current fault, it
enters the fault state.
The TPIC2101 is offered in a 14-terminal plastic DIP (N) package, and a SOIC (D) package, and is characterized
for operation over the operating free-air temperature range of –40°C to 105°C.
