The MAX40203 is an ideal diode current-switch with forward voltage drop that is approximately an order of magnitude smaller than that of Schottky diodes. When forward biased and enabled, the MAX40203 conducts with 90mV of voltage drop while carrying currents as high as 1A. During a short-circuit or a fast power-up, the device limits its output current to 2A. The MAX40203 thermally protects itself and any downstream circuitry from overcurrent conditions.This ideal diode operates from a supply voltage of 1.2V to 5.5V. The supply current is relatively constant with load current, and is typically 300nA. When disabled (EN = low), the ideal diode blocks voltages up to 6V in either direction, makes it suitable for use in most low-voltage, portable electronic devices.The MAX40203 is available in a tiny, 0.77mm x 0.77mm, 4-bump WLP with a 0.35mm bump pitch and a 5-pin SOT23 package. It is specified over the -40°C to +125°C automotive temperature range.ApplicationsBattery Backup SystemsCellular PhonesElectronic ToysNotebook and Tablet ComputersPortable Medical DevicesPowerline Fault RecordersUSB-Powered Peripherals

The MAX40213 is a transimpedance amplifier for optical distance measurement receivers in LiDAR applications. Low noise, high gain, low group delay, and fast recovery from overload make this TIA ideal for distance-measurement applications. Important features include 1.1pA/√Hzinput-referred noise density, an internal 2A input clamp, pin-selectable 150kΩ and 750kΩ transimpedance (into a 1kΩ load), and wide bandwidth (300MHz, typ). An offset current input allows optional adjustment of input offset current. The MAX40213 has a shutdown (SD) control input that reduces the supply current to 0.01μA. This transimpedance amplifier is available in a 8-bump WLP, and is specified over the -40°C to +85°C operating temperature range.ApplicationsIndustrial Safety SystemsLIDAR ReceiversOptical Distance Measurement
