Surveillance Camera Solutions

Toshiba's lineup of MOSFETs, LDO regulators, motor control drivers, photocouplers, and other components use cutting-edge technologies to help designers overcome power consumption challenges in space-constrained designs. This helps in designing highly functional surveillance cameras, which is particularly challenging as they require efficient power management and high signal quality. 

Features:

• Low on-resistance MOSFETs enable high-efficiency operation
• Wide power management IC lineup for improved control of various power management subsystems
• Low operating resistance and low capacitance ensure high signal protection performance and signal quality
• Compliance with safety standards (IEC-62368-1) (eFuse IC)

Camera Power Supply

High withstand voltage and low on-resistance MOSFET are suitable for PWM switching circuits of DC/DC converters. By keeping on-resistance low, heat generation and current consumption can be minimized, and output loss can also be reduced. Toshiba's power MOSFET products use high heat dissipation packages to further reduce heat generation.

In addition, voltage conversion is important for MCUs and SoCs for communication. These are very sensitive to supply voltages, and in some cases, the required performance for transient voltage response is also high. Toshiba's LDO regulators deliver high performance with improved PSRR and load transient response with minimal current consumption, further optimizing power supply circuits.

Camera Storage Interface

As the storage capacity and speed increase, power consumption also increases while SD cards are in use, which means that transient voltage becomes an issue. In addition, SoCs which control SD cards are becoming lower voltage with finer pitch processes. Since the SD card slot is exposed to the outside, the risk of environmental factors is unavoidable. As such, damage caused by electro-static discharge (ESD) poses a high risk.

Toshiba's LDO regulators deliver high performance with improved load transient response with minimal current consumption, enabling SD card power optimization. Toshiba also provides TVS diodes (ESD protection diodes) to protect internal circuits from unexpected ESDs that may damage them. Such TVS diodes are designed to minimize insertion loss and attenuation of electrical signals and are available for signal lines up to 10 Gbps speed.

Recording Unit Storage Powder

Surveillance cameras must operate 24 hours a day, 365 days a year. As such, the power never turns off, but the storage capacity of HDDs and SSDs used in the recording unit is limited. When it’s time to replace full storage devices, it doesn’t power down first. Instead, it’s hot-swapped. This requires features found in Toshiba's eFuse IC which helps protect power lines from hot-swapping side effects like routine power surges, short-circuit, overcurrent, overvoltage, and inrush current suppression. This eFuse IC is IEC62368-1 certified.
