MCP9700T-E/TT
Category: Electromechanical, Temperature, Temperature and Humidity Sensors, Temperature SensorsMicrochip |
Microchip | The MCP9700 sensors with Linear Active Thermistor™ Integrated Circuit (IC) comprise a family of analog temperature sensors that convert temperature to analog voltage.The low-cost, low-power sensors feature an accuracy of ±4°C from 0°C to +70°C while consuming 6 µA (typical) of operating current.Unlike resistive sensors, e.g., thermistors, the Linear Active Thermistor IC does not require an additional signal-conditioning circuit. Therefore, the biasing circuit development overhead for thermistor solutions can be avoided by implementing this low-cost device. The Voltage Output pin (VOUT) can be directly connected to the ADC input of a microcontroller. The MCP9700 temperature coefficients are scaled to provide a 1°C/bit resolution for an 8-bit ADC with a reference voltage of 2.5V and 5V, respectively. The MCP9700 output 0.1°C/bit for a 12- bit ADC with 4.096V reference.The MCP9700 provide a low-cost solution for applications that require measurement of a relative change of temperature. When measuring relative change in temperature from +25°C, an accuracy of ±1°C (typical) can be realized from 0°C to +70°C. This accuracy can also be achieved by applying system calibration at +25°C.In addition, this family is immune to the effects of parasitic capacitance and can drive large capacitive loads. This provides printed circuit board (PCB) layout design flexibility by enabling the device to be remotely located from the microcontroller. Adding some capacitance at the output also helps the output transient response by reducing overshoots or undershoots. However, capacitive load is not required for the stability of sensor output.

VN5050JTR-E
Category: Current Limit Switches, Electromechanical, Gate Drivers, Motor DriversSTMicroelectronics |
STMicroelectronics | The VN5050J-E is a monolithic device made using STMicroelectronics VIPower technology. It is intended for driving resistive or inductive loads with one side connected to ground. Active VCC pin voltage clamp protects the device against low energy spikes (see ISO7637 transient compatibility table). The device detects open load condition both in on and off state, when STAT_DIS is left open or driven low. Output shorted to VCC is detected in the off state.When STAT_DIS is driven high, the STATUS pin is in a high impedance condition.Output current limitation protects the device in overload condition. In case of long duration overload, the device limits the dissipated power to safe level up to thermal shut-down intervention.Thermal shutdown with automatic restart allows the device to recover normal operation as soon as fault condition disappears.
