HT7K1311/HT7K1312

1 Channel, 15V, Peak Current 3A H-Bridge Driver

Features

Applications

• 1 Channel H-Bridge Motor Driver: Low MOSFET

• Electric locks, toys, portable printers

On-resistance: 0.3Ω (HS+LS)

• Wide V_DDInput Voltage Range of 2.5V to 5.5V

• Maximum Motor Power Supply V_M: Up to 15V

• Maximum 3.0A Motor Peak Current

General Description

The HT7K1311/HT7K1312 is a 1-channel H-bridge

driver with a maximum motor peak current of 3.0A.

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 for HT7K1311. However, for HT7K1312

an extra enable pin, EN, directly determines whether

the device enters the Sleep Period. In addition, a low

0.1μA Sleep Period current ensures long battery life.

The device also includes separate power supplies

for the control circuits and the motor power supply

and also includes a current sensing pin to allow the

system to measure the motor current using an external

resistor.

• Four Operation Modes: Forward, Reverse, Brake

and Standby

• Sleep Period Activation Mechanism

♦

HT7K1311: Automatically entering Sleep

Period by resetting both IN1 and IN2 pins for

over 10ms

♦

HT7K1312: Immediately entering Sleep Period

controlled by EN pin

• Low Sleep Current < 0.1μA

• Split Controller and Motor Power Supplies: VDD

and VM

• Isolation Motor Current Sensing Pin: PGND for

HT7K1311 only

• Up to 200kHz PWM Input Control Operation

• Internal Pull Down Resistor

♦

IN1/IN2: 135kΩ for HT7K1311/HT7K1312

♦

EN: 12kΩ for HT7K1312 only

• Protection Features:

♦

V_DDUnder Voltage Lock-Out

♦

Over Current Protection

♦

Thermal Shutdown Protection

♦

Output Short Circuit Protection

• Package Type
