SSP8023A

SSP8023A is a bi- direction relay driver circuit, used to control the DC motor and the magnetic latching relay, with large output capability, ultra- low power consumption. It can be widely used in smart meters and other pulses, level control applications.

Applications

• Smart Meter
• Motor drive
• Magnetic latching relay control

Key features

• Max input voltage: 40V, recommended safe working voltage: 5 - 24V
• Pure MOSFET, compared with ordinary BJT triode circuit power consumption is lower
• Quiescent current < 10nA
• The input high low conversion level is about 2.6V, which is compatible with various microcontrollers
• The input INA and INB are equipped with pull-down resistors of about 100K
• Integrated high speed continuation diode with built-in reverse voltage function to cancel TVS tubes in general applications
• The typical drive current is 400mA, and according to the different coil internal resistance of the relay itself (drive current is equal to the power supply voltage divided by the chip itself drive internal resistance and the combination of the relay coil internal resistance, the chip itself drive internal resistance; 12Ω when the power supply voltage is 12V, 11Ω when the power supply voltage is 30V)
• Maximum drive current 800mA (refers to the chip can withstand the value of the relay coil inductor recoil current. The value is dependent on the supply voltage. 800mA refers to the general operating voltage of 12V. In the limit operating voltage of 24V, the driving current should be less than 200mA)
