PT12465A Datasheet 16v/0.8a Stepping Motor Driver

Manufacturer: PTC

Overview: Preliminary PT12465A CLK-in, 16V/0.8A stepping motor driver.

Datasheet Details

The PT12465A is a stepping motor driver, the Hbridges output current controlled by PWM constantcurrent topology.

Built-in micro-step sequencer could generate sinusoidal output current to the stepping motor by a single clock input.

The PT12465A support multiple excitation modes such as 2-phase, 1-2-phase, W1-2-phase and 2W1-2 phase mode.

AEC-Q100 Grade 2 qualified, operation temperature range -40°C~105°C.
Motor power supply voltage range: - Control (VCC): 2.7V to 5.5V - Motor (VM): 2.5V to 16V.
Maximum output current: 0.8 A.
H-bridge switches on-resistance: Ron = 1.5Ω (high side + low side, VM=7 V).
Built-in microstep sequencer ticking by CK clock signal.
Programmable phase current excitation modes (2 phase, 1-2 phase, W1-2 phase and 2W1-2 phase).
Control input pins with internal pull-down res.
