Product Introduction
- H-bridge circuit topology with integrated N-channel and P-channel power MOSFETs, optimized for driving inductive loads such as coils and motors.
- Integrated over-temperature protection: shuts off load current when internal temperature exceeds the set threshold (typical 150°C); resumes normal operation when junction temperature drops back to the preset level (typical 130°C). Note: no short-circuit protection is provided — output-to-GND, output-to-supply, or output-to-output shorts may cause device damage. Avoid short-circuit conditions during use, or implement current-limiting measures to prevent such damage.
- Logic supply VCC and power supply VDD are fully independent internally. Route them separately in layout; do NOT connect VCC and VDD directly together, as the high voltage on VDD may damage the VCC rail.
Features
- Low standby current (< 0.1uA)
- Operating voltage range: 2V - 8.6V
- Maximum continuous output current: 1.4A (VDD = 6.5V)
- Maximum peak output current: 3A (VDD = 6.5V)
- Low on-resistance — 0.35Ω at 1400mA output current; 0.3Ω at 200mA output current
- Low input current — logic inputs INA\INB with integrated 15K pull-down resistors to GND
- Built-in thermal shutdown (TSD) with hysteresis
- ESD rating: 4KV (HBM)
Applications
- - Toy motor driver powered by 2 4 AA/AAA dry cell batteries - Toy motor driver powered by 2 5 NiMH/NiCd rechargeable batteries - Motor driver powered by 2-cell lithium battery
