1 Channel, 6.0V, Peak Current 1.3A H-Bridge Driver

Features

Applications

• 1 Channel H-bridge motor driver: low MOSFET

• Valve/Pump, electric locks and consumer toys

on-resistance: 0.5Ω (HS+LS)

• Wide V_DDinput voltage range of 1.8V to 6.0V

• Maximum 1.3A motor peak current

General Description

The HT7K1201 is a 1-channel H-bridge driver

with a maximum motor peak current of 1.3A. Its

outstanding low on-resistance characteristic results

in excellent output efficiency which is a major

advantage in battery powered systems. A simple two

input control pin structure is used to provide four

control modes: Forward, Reverse, Brake and Standby

modes. With a PWM input control frequency of up to

200kHz, accurate speed control can be implemented

for a wide variety of applications. A full range of

protection functions are integrated including OCP,

OSP and OTP to prevent device damage even if the

motor stalls or experiences a short circuit in critical

operating environments. As the automatic sleep period

activation mechanism uses the same mode control

pins, an additional extra shutdown signal is not

required. In addition, an ultra-low 0.1μA sleep period

current ensures long battery life.

• Four operation modes: Forward, Reverse, Brake

and Standby

• Low sleep current < 0.1μA

• Sleep period activation mechanism

♦

Automatically entering sleep period by resetting

both IN1 and IN2 pins for over 10ms

• Up to 200kHz PWM input control operation

• Protection features

♦
