The TPL7407LA-Q1 is a high-voltage, high-current NMOS transistor array. This device consists of seven NMOS transistors that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The maximum drain-current rating of a single NMOS channel is 600 mA. New regulation and drive circuitry added to give maximum drive strength across all GPIO ranges (1.8 V–5 V).The transistors can be paralleled for higher current capability. The TPL7407LA-Q1 key benefit is its improved power efficiency and lower leakage than a Bipolar Darlington Implementation. With the lower VOLthe user is dissipating less than half the power than traditional relay drivers with currents less than 250 mA per channel.

The TPL8002-25 is a programmable resistor device implementing two digital potentiometers with 64 wiper positions each that are tandem controlled through a 6-bit parallel interface. The device has fixed wiper resistances at the respective wiper contacts that tap the potentiometer resistors at a point determined by the binary code present at its digital inputs. The resistive wiper tap terminals, RSW, of the TPL8002-25 are typically connected to the inverting inputs (–) of an external differential path inverting operational amplifier configuration, with the non-inverting inputs (+) connected through to ground. The application’s differential input to the configuration is the device’s RG terminals. The differential output of the external operational amplifiers is connected to the device’s RF terminals, and thus becomes the differential output of the application configuration. The resistance between the wiper contacts and the end points RG and RF of the TPL8002-25 provides a logarithmic gain/attenuation response of the configuration. With a digital code of decimal 0 (b000000) the configuration has an inverting maximum attenuation of –24 dB. With a digital code of decimal 32 (b100000) the configuration has inverting unity gain of 0.00 dB. With a digital code of decimal 63 (b111111) the configuration has an inverting maximum gain of +23.25 dB. The response of the configuration with respect to the digital code varies in fixed steps of 0.75 dB.

The power supply provides regulated 5-V output to power the system microcontroller and drive eight low-side switches. The AC zero-detect circuitry is monitoring the crossover voltage of the mains AC supply. The resultant signal is a low-frequency clock output on the ZVS terminal, based on the AC-line cycle. This information allows the microcontroller to reduce in-rush current by powering loads on the AC-line peak voltage. A serial communications interface controls the eight low-side outputs; each output has an internal snubber circuit to absorb the energy in the inductor at turn OFF. Alternatively, the system can use a fly-back diode to VINto help recirculate the energy in an inductive load at turn OFF.

The TPPM0110 is a power source intended for use in systems that have a single 5-V input source and require dual, linearly-regulated, low-dropout voltage sources. The outputs must track within 2 V of each other during all conditions and modes of operation. Each output is protected against overcurrent conditions.
