BL5612 1.5A, 3.0-25.0V H-Bridge Driver Description Features The BL5612 is one channel H-Bridge driver IC, it provides integrated motor-driver solution for toys, robotics, consumer products and other low voltage or battery-powered motion control applications. ⚫ ⚫ ⚫ ⚫ ⚫ ⚫ ⚫ ⚫ ⚫ The BL5612 maximum operational voltage is 25.0V. It can supply up to 1.5A of output continuous current and 3.5A of output peak current. There is internal shutdown function for over-temperature protection and over-current protection (IOCP = 4.5 A). Operation voltage range up to 25.0V Maximum continuous current output up to 1.5A Low RDS(ON) for highly efficient H-bridge output. Support PWM control Over current protection Over temperature protection Low standby current Low quiescent current SOP8 package Application ⚫ Package material is Pb-Free Product & RoHS compliant for the purpose of environmental protection and for sustainable development of the earth. ⚫ ⚫ Robotics (R/C servo, Sweeping robot) Toys (R/C car, R/C aircraft) Any relevant DC motor applications.

Schematic Descriptions Notes : 1. This simplified schematic is only as reference in DC motor driver application. 2. C0,C1: Power supply VM pin capacitor: 1) The capacitor can reduce the power spike when the motor is in motion. To avoid the IC directly damaged by the VM peak voltage. It also can stabilize the power supply voltage and reduce its ripples. 2) The C0 capacitor can compensate power when motor starts running. 3) The capacitor value determines the stability of the VM during motor in motion. If the large voltage power or a heavy loading motor is used, then a larger capacitor would be needed. 4) On the PCB configuration, the C0,C1 must be mounted as close as possible to VM pin . 3. C2:The across-motor capacitor 1) The C2 capacitors can reduce the power spike of motor in start running. A 0.1μF capacitor is recommended. 2) The C2 capacitor must be added to the general application. 4. RS: The sense resistor in current sense application 1) Need to sense output current, the RS is recommended to added between IC GND and PCB ground. 2) The C0, C1 negative terminal is recommend connection to IC GND. www.belling.com.cn 5 V1.0 BL5612 2. Operating Mode Descriptions H-Bridge basic operating mode: A) Stop mode Definition:When INA=INB= L, then OUTA=OUTB=Hi-Z B) Forward mode Definition:When INA=H, INB=L, then OUTA=H, OUTB=L C) Reverse mode Definition:When INA=L, INB=H, then OUTB=H, OUTA=L D) Brake mode Definition:When INA=INB= H,then OUTA=OUTB=L 3. Protection Mechanisms Descriptions 1) Over-current protection (OCP) While the IC conducts a large current, 4.5A (Typ.), the internal over-current protection function will be triggered. The device enters protection mode of auto-recover to avoid damaging IC and system. 2) Over-temperature protection If the IC junction temperature exceeds 180 °C (Typ.), the internal over-temperature protection function will be triggered, partial FETs in the H-bridge are disabled, that will ensure the safety of customers' products. If the IC junction temperature falls to 120 °C(Typ.), the IC resumes automatically. www.belling.com.cn 6 V1.0 BL5612 Package SOP8 www.belling.com.cn 7 V1.0
