Product Summary
The LB1938T-TLM is an H-bridge motor driver that supports low-voltage drive and features low-saturation outputs in an ultraminiature slim package. The LB1938T-TLM provides forward, reverse, brake, and standby modes controlled by two input signals, and is an optimal DC motor driver for notebook personal computers, digital cameras, cell phones, and other portable equipment.
Parametrics
LB1938T-TLM absolute maximum ratings: (1)Allowable power dissipation: 400 mW; (2)Operating temperature range: -30 to +85 °C; (3)Storage temperature range: -55 to +150 °C; (4)Supply voltage: 2.2 to 10 V; (5)Input high-level voltage: 2.0 to 9.5 V; (6)Input low-level voltage: -0.3 to +0.3 V; (7)Spark killer diode forward voltage: 1.7 V; (8)Spark killer diode inverse current: 5 μA; (9)Input current: 98 μA.
Features
LB1938T-TLM features: (1)Ultraminiature MSOP8 package; (2)The wide usable voltage range and the low standby mode current drain of 0.1 μA make this IC optimal for battery operated equipment.; (3)There are no constraints on the relationship between the input signal voltage and the supply voltage. For example, this IC can be use at VCC = 3V and VIN = 5V.; (4)Thermal protection circuit limits the drive current and prevents the IC from causing a fire or being destroyed if the IC chip temperature reaches or exceeds 180°C due to large currents flowing when the outputs are shorted due to, for example, motor layer shorting or other phenomena.
