Dual Full-Bridge Driver for DC Motor
TB62300FG
The TB62300FG is a dual brushed DC motors driver IC
employing a chopper-based forward/reverse full-bridge
mechanism. It controls two brushed DC motors at high precision.
The motor supply voltage is up to 40 V and the V_DD supply
voltage is 5.0 V.
Features
• A single IC can drive two brushed DC motors.
• Monolithic Bi-CMOS IC
• Low ON-resistance (R_on) = 0.3 Ω (T_j = 25°C at 2.0 A typ.)
• Selectable current control: PWM current control using the
PHASE pin or serial control
Weight: 0.79 g (typ.)
• 5-bit DA converter for specifying current value and 2-bit DA converter for determining torque
• MIXED DECAY mode enables specification of current decay rate in four steps.
• Self-oscillation chopping frequency with external resistor and capacitor
• High-speed chopping at 100 kHz or higher
• ISD, TSD, and POR (V_DD/V_M) protection circuits
• Charge pump circuit (two external capacitors) for driving output
• 36-pin package: HSOP36 with heat sink
• Output voltage: 40 V (max)
• Output current: 2.5 A max (in steady-state phase) or 8 A max (pulsed output)
