1 / 21 page TB6674PG/FG/FAG Ver.3 2010-07-07 1 TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB6674PG, TB6674FG, TB6674FAG Stepping Motor Driver IC TB6674PG, TB6674FG, and TB6674FAG are stepping motor driver ICs with MOS output transistors. The ICs can control two-phase stepping motor forward and reverse by bipolar driving. They have a power-saving circuit and a standby circuit. Features They are similar substituting products of TA7774PG, TA7774FG, and TA7774FAG. Both products have same packages and same pin assignments. One-chip two-phase bipolar stepping motor driver (including two bridge drivers) Power saving operation is available. Standby operation is available. Current consumption ≤ 20 μA (typ.) Built-in punch-through current restriction circuit for system reliability and noise suppression. TTL-compatible inputs INA, INB, PS, and Vs2B terminals ON resistance PS = L : 2.9 Ω (Typ.) PS = H: 7.9 Ω (Typ.) High driving ability. <TB6674PG/FG> : IO (START) 350 mA (MAX.) : VS1 ENABLE : IO (HOLD) 100 mA (MAX.) : VS2 ENABLE <TB6674FAG> : IO (START) 100 mA (MAX.) : VS1 ENABLE : IO (HOLD) 50 mA (MAX.) : VS2 ENABLE Typical PKG DIP16 pin, HSOP16 pin, SSOP16 pin GND terminal = HEAT SINK Process :BiCD0.6 (30 V) Over current shutdown circuit (ISD). Thermal shutdown circuit (TSD). Undervoltage lockout circuit (UVLO). Pull-down resistance for input terminal (250 kΩ). TB6674PG TB6674FG TB6674FAG Weight DIP16-P-300-2.54A: 1.11 g (typ.) HSOP16-P-300-1.00: 0.50 g (typ.) SSOP16-P-225-1.00A: 0.14 g (typ.) The following conditions apply to solderability: About solderability, following conditions were confirmed (1)Use of Sn-37Pb solder Bath ·solder bath temperature: 230℃ ·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℃ ·dipping time: 5 seconds ·the number of times: once ·use of R-type flux |
