TB6559FG
Full-Bridge DC Motor Driver IC
TB6559FG
The TB6559FG is a full-bridge DC motor driver with LDMOS
output transistors.
It uses P-channel MOSFETs on the high side and N-channel
MOSFETs on the low side, eliminating the need for a charge
pump. The TB6559FG achieves high thermal efficiency.
Four operating modes are selectable via IN1 and IN2: clockwise
(CW), counterclockwise (CCW), short brake and stop.
Features
Power supply voltage: 50 V (max)
Output current: 2.5 A (max)
Low-ON resistance (upper and lower sum): 1.3 Ω (typ.)
Constant-current or direct PWM
Standby mode
Clockwise (CW), counterclockwise (CCW), short brake and stop
Overcurrent protection
Thermal shutdown
Weight: 0.50 g (typ.)
The TB6559FG uses Sn-Ag plating free of lead.
About solderability, following conditions were confirmed
(1) Use of Sn-37Pb solder Bath
· solder bath temperature = 230°C
· dipping time = 5 seconds
· the number of times = once
· use of R-type flux
(2) Use of Sn-3.0Ag-0.5Cu solder Bath
· solder bath temperature = 245°C
· dipping time = 5 seconds
· the number of times = once
· use of R-type flux
