TB67H303HG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB67H303HG Full Bridge Driver IC for DC motor TB67H303HG The TB67H303HG is a full bridge driver IC for DC motor adopting MOS in output transistor. High-power and high-efficient drive is possible by adopting DMOS output driver with low-ON resistance and PWM drive. Features Full bridge driver IC for DC motor HZIP25-P-1.00F Ron (upper + lower) = 0.2 (typ.) Weight CW/CCW/Short brake/Stop functions HZIP25-P-1.00F: 7.7g (typ.) Standby function PWM control (Direct PWM or Constant-current PWM drive) Output withstand voltage : Vcc = 50 V Output current : I = 10.0 A (Absolute maximum ratings, peak) OUT I = 8.0 A (operating range, maximum value) OUT Package : H Z IP 25 -P-1.00F Built-in input pull-down resistance : 100 k (typ.) Output monitor pin (monitor for TSD/ISD) : ALERT1 pin (IALERT1 (max) = 1 mA) Output monitor pin (monitor for UVLO) : ALERT2 pin (IALERT2 (max) = 1 mA) Single power supply Built-in thermal shutdown (TSD) circuit Built-in under voltage lock out (UVLO) circuit Built-in over-current detection (ISD) circuit 1 2016-06-07 TB67H303HG Pin Functions Pin No. I/O Symbol Functional Description Remark 1 Output ALERT1 TSD / ISD monitor pin Pull-up by external resistance 2 SGND Signal ground Select pin for constant-current PWM or 3 Input SELECT direct PWM 4 (TEST1) Shipping inspection pin Connect to SGND 5 Input Vref Voltage input for 100% current level 6 Input Vcc Power supply 7 Input STBY Standby pin H Start, L Standby 8 Input IN1 Control input pin 1 9 Input IN2 Control input pin 2 10 Output OUT2B Bch output 2 11 RSB Bch output current detection 12 Output OUT1B Bch output 1 13 PGNDB Power GND 14 Output OUT2A Ach output 2 15 RSA Ach output current detection 16 Output OUT1A Ach output 1 17 PGNDA Power GND 18 (TEST2) Connect to SGND Shipping inspection pin 19 (TEST3) Shipping inspection pin Connect to SGND 20 Input Vcc Power supply 21 (TEST4) Shipping inspection pin Connect to SGND 22 Input PWM PWM signal input pin Resistor connection pin for internal 23 OSC oscillation setting Control side connection pin for power 24 Output Vreg Connecting capacitor to SGND capacitor 25 Output ALERT2 UVLO monitor pin Pull-up by external resistance (TEST1), (TEST2), (TEST3) and (TEST4): Shipping inspection pins.
