L9960 L9960T Automotive Single/Dual H-Bridge, SPI programmable DC Brushed Motor Driver Datasheet - production data Short circuit and programmable thermal warning and shutdown thresholds Open Load diagnosis in ON condition All I/O pins can withstand up to 19 V SPI interface for configuration and diagnosis GAPGPS00337 Two independent enable/disable pins NDIS PowerSSO-36 and DIS and SOPC (Switch-off Path Check) available Spread Spectrum function for EMI reduction Features Available in single (L9960) and Twin (L9960T) AEC-Q100 qualified option, both in PSSO36 package Flexible driving strategy via configurable pins PWM/DIR (IN1/IN2) Description RDSon < 400 m (full path at T =150 C) j The device is an integrated H-Bridge for resistive Operating battery supply voltage from 4.5 V up and inductive loads for automotive applications. to 28 V Target application includes throttle control Operating VDD5 supply voltage from 4.5 V to actuators, exhaust gas recirculation control 5.5 V valves and general purpose DC motors such as turbo, flap control and electric pumps. Input switching frequency up to 20 kHz The driving strategy is enhanced by configurable Built in charge pump supporting 100% duty PWM / DIR pins and IN1/IN2. cycle Logic levels compatible to 3.3 V and 5 V The H-Bridge contains integrated free-wheel diodes. In case of freewheeling condition, the Monitoring of VDD5 supply voltage with low-side only is switched on in parallel of its diode bidirectional switch-off pin to reduce power dissipation. Current limitation SPI-adjustable in four steps. The integrated Serial Peripheral Interface (SPI) Output stage current limitation with makes it possible to adjust device parameters, to dependence on temperature control all operating modes and read out 2 Programmable voltage and current slew rate diagnostic information. control Table 1.
