STSPIN840

STSPIN840 is a compact brushed DC motor driver able to drive two bi-directional brushed DC motors simultaneously. Due to a dedicated PARALLEL input pin the parallel mode function can be enabled, transforming the device in an equivalent and more powerful single full-bridge able to deliver up to 3Arms current at an equivalent HS + LS RDSon of 500mohm. This embeds two independent PWM current controllers (one for each full bridge) based on user settable Values of reference voltage and OFF time. The device can be forced in a low consumption state reducing the total current consumption down to less than 45µA. Applications include industrial automation and service robots, medical and health care, ATM and money handling machines, stage lighting, thermal printers, textile and sewing machines, vending machines, office and home automation.

• Operating voltage from 7 to 45V
• 1.5Arms continuous power stage output current (each full bridge)
• Current control with adjustable OFF time
• Current sensing based on external shunt resistors
• Full protections set, non-dissipative overcurrent protection
• Short-circuit protection, undervoltage lockout, thermal shutdown
• Low standby current consumption
• 6.0V typicalVS turn-on threshold (VS rising from 0V, VS = 36V, Tj = 25°C)
• 2.3mA typicalVS supply current (No commutations ENx = '0' RTOFF = 10kohm)
• 24 lead TFQFPN, junction temperature range from -40 to 150°C
