Detailed Pin Configuration

The MAX16004BTP+T has the following pin configuration:

1. GND: Ground connection
2. RESET#: Active-low reset output
3. MR#: Manual reset input
4. VCC: Positive power supply input
5. TH: Threshold voltage selection input
6. TO: Reset timeout selection input

Functional Features

• Generates a reset signal when the voltage drops below the selected threshold
• Provides manual reset capability through the MR# pin
• Adjustable threshold voltage and reset timeout options for flexibility
• Low quiescent current consumption for power efficiency

Advantages and Disadvantages

Advantages

• High accuracy in monitoring power supply voltage
• Low power consumption, suitable for battery-powered applications
• Small package size allows for space-constrained designs
• Flexible threshold voltage and reset timeout options

Disadvantages

• Limited supply voltage range (1.6V to 5.5V)
• Not suitable for high-temperature applications above +85°C

Working Principles

The MAX16004BTP+T operates by continuously monitoring the power supply voltage through the TH pin. When the voltage falls below the selected threshold, the RESET# pin is asserted low, indicating a reset condition. The reset signal remains active until the voltage rises above the threshold or a manual reset is triggered through the MR# pin. The TO pin allows selection of the reset timeout duration.
